Humaneness PerformanceNet · Shared taxonomy library

The Humaneness Script Analysis System authors performance inputs from source material. The Humaneness Performance Annotation System describes generated or recorded performance. Shared taxonomies connect prompting, annotation, representation and data selection.

Reader’s guide

Listen for the quality; use its own scale

VoiceNet is the specialist voice taxonomy within Humaneness PerformanceNet. It complements the body, interaction and multimodal fields in the PerformanceNet Taxonomy and the emotional vocabulary in the EmoNet Taxonomy.

Inventory	Reading rule
55 fields	Each has seven written anchors, 0–6. Use the actual direction and intermediate descriptions; higher is not always better, louder or more intense.
Background Noise	BKGN has five anchors, 0–4. Higher means less ambient noise. The source supplies no 5 or 6.
Content Appropriateness	EXPL has three anchors, 0–2. The audience labels require an explicit audience and use context.
Missing evidence	Keep `null` and its reason when no supported value is available. The zero anchor is a real value.

The source introduction describes all fields as seven-level scales. Its actual tables contain the two exceptions above; this reference preserves those tables instead of inventing missing levels.

The source inventory is explicit. This pinned primary codebook supplies 57 fields. The inherited PerformanceNet master separately mentions 59 VoiceNet-Ext attributes. A verified 59-field codebook and exact 57-to-59 crosswalk are not supplied here, so this volume does not claim to contain or reconcile them.

One vocabulary across the workflow

In the Humaneness Script Analysis System, source material informs Character Makeup, scene obligations including Emotional obligations, and ordered Acting Beats with one Experience Chunk each. The resulting prompt guides an AI actor to generate audio or audio with video. In the Humaneness Performance Annotation System, an observer describes the resulting performance, or a reference recording, using available evidence.

Keep requested targets, observed labels and observer judgments in separate fields. Their shared vocabulary supports prompt construction, searchable annotation, model representations and diverse data selection. A downstream reward model needs a declared target, task and calibration; the taxonomy alone supplies neither a trained model nor a universal quality score.

Pair these fields with the PerformanceNet Situation Taxonomy when selecting scene contexts. A taxonomy coordinate does not establish that a recording exists or that the intended combination has been achieved.

What this codebook can and cannot establish

Definitions and anchors below retain the primary source wording. Some anchors describe physiology, cognition, speaker identity or idealized aesthetics. Treat these as inherited descriptions of a perceived or performed quality. A voice rating does not establish a person’s biological state, gender identity, actual age, diagnosis or private feeling. Local reading notes make this boundary explicit where needed.

Style fields can overlap. Acoustic Warmth concerns timbre rather than social affection. Resonance-placement names describe perceived sound rather than verified anatomy. Separate microphone, room and recording effects from speaker behavior whenever the evidence allows.

Use each field independently with an interval, evidence access and confidence. For learning or reward targets, declare which dimensions and values the task calls for; indiscriminately maximizing or averaging the scales would change their meaning. Neither the vocabulary nor its inherited framework attribution establishes a trained model’s accuracy.

Names, codes and abbreviations

The large title supplies the human name; the small code is the stable machine identifier. ASMR means autonomous sensory meridian response and here labels a speaking style. In the audience scale, SFS means Safe for School, SFW Safe for Work and NSFW Not Safe for Work. These source audience labels require contextual interpretation.

The structured registry retains every definition and anchor, with the unmodified primary codebook and its Apache-2.0 license. New navigation, Humaneness guidance and evidence notes are editorial additions.

TEMP · Written source anchors 0–6

Tempo

Measures the mechanical speed of word and syllable production

Value	Tempo · `TEMP` · source anchors
0	The speech is glacially slow, with syllables stretched to their absolute breaking point to create a near-static acoustic environment. Each isolated word floats in heavy silence, lacking standard linguistic momentum. The fundamental velocity of the vocal apparatus is labored and drawn out, making the linguistic content nearly unrecognizable.
1	The word production is unusually deliberate and labored, characterized by excessive time taken to resolve every single phoneme. The pace feels incredibly heavy and sedate, creating a dragging, low-density acoustic stream with greatly elongated vowel durations. It sounds like someone reading a solemn decree or struggling through deep lethargy.
2	The vocal delivery is relaxed and unhurried, moving at a pace slightly below the conversational average but maintaining functional momentum. Syllables are articulated comfortably without any sense of compression, rush, or artificial urgency. The overall acoustic speed is comparable to a gentle storyteller or a patient teacher explaining a concept.
3	The audio features a standard, unremarkable human speech tempo typical of an everyday, efficient conversation. The linguistic density and syllable rate are perfectly balanced, creating a comfortable and natural acoustic flow. There is no perceived stretching or squeezing of the phonemes.
4	The speech has a brisk, elevated momentum that suggests high engagement and a healthy forward conversational push. Syllables are delivered with slight forward energy without sounding panicked or artificially rushed. The linguistic stream moves swiftly and efficiently, keeping the listener highly engaged.
5	Words and syllables are noticeably compressed, running into each other to create a fast, high-density stream of acoustic information. The speaker is vibrating with rapid physical energy, forcing the vocal apparatus to move at a highly accelerated velocity. This rapidly trims all excess duration from the vowels, making the listener work hard to track the phonemes.
6	The tempo reaches the absolute human limit of linguistic speed, resulting in a blistering, hyper-accelerated wall of sound. Phonation is extremely dense, causing individual word boundaries to completely blur into a continuous, high-velocity acoustic vibration. The delivery sounds like a professional auctioneer or an individual in a state of high-speed panic.

CHNK · Written source anchors 0–6

Chunking

Describes how the speaker groups words into breath units and pause frequency

Value	Chunking · `CHNK` · source anchors
0	The speech is severely fragmented into single syllables or isolated words, broken apart by massive, jarring gaps of silence. It sounds like a malfunctioning vocal mechanism or someone physically struggling to piece together a single thought. There is absolutely no continuous respiratory flow or cohesive acoustic phrasing present.
1	The audio consists of very short, choppy two-word bursts that create a percussive, stop-and-go rhythmic structure. Every minor thought is separated by distinct, unnecessary pauses that completely interrupt the natural breathing cycle. The overall acoustic effect is highly disjointed and lacks any continuous flow.
2	Breath units are consistently shorter than natural phrasing, characterized by cautious, highly separated groupings of words. The speaker frequently pauses after small clauses, breaking the sentence into small, easily digestible acoustic blocks. This results in a pedantic, heavily segmented delivery style that feels artificially paced.
3	The speech is grouped into natural, medium-length sentence-sized clauses that align perfectly with standard human breath cycles. Pauses occur naturally at grammatical boundaries, creating an easy-to-follow, balanced conversational rhythm. The respiratory management and acoustic spacing feel completely unremarkable and organically structured.
4	The phrasing is noticeably extended, often linking multiple sentences together into a single, continuous, sweeping breath unit. The speaker utilizes high lung capacity to bridge normal stopping points, creating a smooth, long-range acoustic flow. Pauses are infrequent but deliberate, supporting a large-scale structural delivery.
5	The audio features very long, dense streams of words poured out with only the briefest of snatched inhalations. The linguistic density between pauses is incredibly high, driven by an urgent need to finish large thoughts without resting. This creates a relentless, unbroken wave of speech that stretches the limits of normal breath support.
6	The speaker produces a massive, continuous wall of words that lasts the entire duration of the audio clip without a single pause or breath. It is a relentless, unrelenting flood of dense linguistic output that offers absolutely no acoustic gaps for rest or processing. The listener is overwhelmed by the sheer, uninterrupted continuity of the vocalization.

SMTH · Written source anchors 0–6

Smoothness

Gauges the regularity of timing grid and fluidity of transitions between linguistic units

Value	Smoothness · `SMTH` · source anchors
0	The rhythmic timing of the speech is completely chaotic and spasmodic, filled with random, jarring glitches and acoustic micro-stops. The vocal delivery moves in disconnected, highly irregular pulses that suggest severe vocal instability or mechanical breakdown. There is an absolute lack of continuous, predictable acoustic flow.
1	Every syllable is sharply detached from its neighbor, creating a percussive, staccato, machine-gun-like acoustic effect. The timing is extremely rigid, with a total lack of fluid connection or legato transition between sounds. The delivery feels intensely harsh and mathematically segmented into isolated acoustic hits.
2	The rhythmic grid is uneven and bumpy, characterized by frequent micro-hesitations and clumsy acoustic transitions. The speech lacks a steady, predictable pulse, sounding like an unprepared or organically flawed read. The acoustic envelope stumbles awkwardly from word to word without natural grace.
3	The audio features the standard, slightly flexible rhythm of natural human speech, complete with minor, organic timing imperfections. It flows smoothly but retains the natural breathing and slight elasticity characteristic of spontaneous thought processes. The timing is comfortable, balanced, and conventionally fluid.
4	The speech timing is noticeably consistent, practiced, and regular, locking into a predictable and pleasing rhythmic pulse. It sounds like the highly controlled delivery of a professional narrator who smoothly connects phrases with practiced ease. The transitions between words are clean, measured, and highly stable.
5	The vocal delivery flows like silk, featuring a beautiful, continuous, wave-like legato quality in the acoustic signal. Every word melts seamlessly into the next with exceptional grace and perfectly modulated timing transitions. The rhythmic structure is highly pleasing, fluid, and entirely uninterrupted by micro-stops.
6	The rhythm is mathematically perfect and entirely metronomic, completely devoid of natural human timing deviations. The delivery sounds highly mechanical, like a high-end digital synthesizer or an AI (artificial intelligence) voice strictly locked to a digital quantization grid. It possesses an inhuman, flawless acoustic regularity that feels completely sterile.

CLRT · Written source anchors 0–6

Articulation Clarity

Measures the precision with which consonants and vowels are produced

Value	Articulation Clarity · `CLRT` · source anchors
0	The speech is an indecipherable, blurry hum where distinct consonants and vowel boundaries are completely invisible in the acoustic signal. It sounds like a heavily muffled voice heard through a thick wall, lacking any high-frequency transient bites. The listener cannot extract any clear phonemes from this continuous, mushy sound wave.
1	Consonants are severely swallowed and lack all precision, resulting in a heavily mumbled, fuzzy acoustic texture. The word boundaries are entirely soft, sounding like the speaker is heavily sedated or speaking with a highly restricted oral cavity. The severe lack of articulatory effort makes acoustic transcription incredibly difficult.
2	The articulation is consistently soft and overly relaxed, lacking the crisp transient edges typical of active communication. While most words are intelligible, the overall delivery is mushy, similar to tired, domestic mumble-core speech. The vocal apparatus is applying minimal physical effort to shape the sound waves.
3	The audio exhibits a neutral, standard level of articulation perfectly suited for everyday, clear acoustic communication. Words are easily separable with well-defined vowel shapes and appropriately struck consonants. The speaker puts in just enough mechanical effort to be naturally understood without sounding overly precise.
4	Every syllable is pronounced with crisp, distinct clarity, ensuring highly intelligible and clean phoneme boundaries. The consonants have a clear, precise bite, typical of a high-quality, professional narrator focused on maximum audio legibility. The delivery is sharp and clean without crossing into artificial exaggeration.
5	The articulation is incredibly precise and deliberate, with consonants carved out using high physical energy and perfectly shaped vowels. It has the sharp, commanding acoustic clarity of a classically trained stage actor or an elite broadcaster. Every acoustic boundary between sounds is meticulously managed and highly defined.
6	The phonemes are hyper-articulated to an extreme, unnatural degree, completely over-enunciating every single consonant and vowel. The delivery sounds like a rigid caricature of a formal speaker, with exaggerated plosive pops and sharply cut word endings. This level of mechanical precision is highly distracting and completely abandons organic human blending.

RANG · Written source anchors 0–6

Pitch Range

Describes the vertical movement of fundamental frequency across the segment

Value	Pitch Range · `RANG` · source anchors
0	The fundamental frequency remains on a perfectly flat, horizontal line with absolutely zero micro-tonal deviation. The voice is completely devoid of melodic movement, sounding like a singular synthetic beep or a completely lifeless drone. It represents the absolute mathematical minimum of pitch variance in an acoustic signal.
1	The pitch exhibits only microscopic, severely suppressed movements, hovering heavily around a single monotonous baseline note. The vocal melody feels clinical, drained of energy, and aggressively flattened out. It is a highly restricted acoustic profile that completely lacks natural frequency inflection.
2	The intonation moves within a very narrow, highly controlled, and restrained fundamental frequency window. Pitch rises and falls are present but intentionally minimized, typical of a speaker remaining intensely calm or delivering dry technical instructions. The acoustic melody is functional but kept strictly clamped down.
3	The audio features the moderate, standard intonation range of a typical human conversation, complete with organic pitch rises and falls. The fundamental frequency moves smoothly across a standard melodic window, emphasizing thoughts naturally. It is a balanced, conventionally expressive acoustic contour.
4	The pitch moves expressively across a wide range of notes, actively utilizing significant fundamental frequency highs and lows to project personality. The voice sounds lively, colorful, and deeply engaged, creating a dynamic and engaging melodic map. The sweeping pitch jumps clearly highlight the emotional intent of the speaker.
5	The delivery is highly melodic, characterized by sweeping, dramatic pitch jumps and beautifully pronounced sing-song contours. The voice utilizes nearly its full musical range, bouncing rapidly between high acoustic peaks and deep valleys. It possesses the vibrant, animated theatricality of a professional voice actor or storyteller.
6	The pitch swings wildly and hyperbolically between the absolute extreme highs and lows of the speaker's vocal register. It is an aggressively stylized, operatic delivery that sounds larger than life and entirely theatrical. This massive variance in fundamental frequency creates a highly exaggerated, nearly musical vocal performance.

EMPH · Written source anchors 0–6

Emphasis

Refers to how the speaker creates informational hierarchy by stressing specific words or syllables

Value	Emphasis · `EMPH` · source anchors
0	Every single word is delivered with identical acoustic weight, perfectly flat volume, and exactly uniform duration. There is absolutely no informational hierarchy, making the speech sound like an unanchored, monotonous list of syllables. The complete absence of dynamic stress renders the sentence entirely flat.
1	The emphasis is incredibly weak, with only the faintest, nearly undetectable shifts in volume or pitch to mark key words. The hierarchy of information is deeply buried, making it difficult to discern the core focus of the sentence through the audio alone. The dynamic delivery feels aimless and severely under-stressed.
2	Important words are only lightly and subtly marked by minor increases in vocal energy or slight pitch bumps. This gentle emphasis provides a basic, low-stakes structural map for the listener to follow the logic. It is a soft, polite acoustic hierarchy without any aggressive highlighting.
3	The speech features a clear, natural emphasis pattern where key informational anchors are distinctly and comfortably stressed. The listener can immediately identify the core message through organic, well-placed spikes in acoustic volume and pitch. The dynamic weighting is perfectly balanced for everyday comprehension.
4	The speaker heavily and effectively marks important words, creating a strong, highly structured acoustic hierarchy. Key concepts are underlined with distinct vocal force, elongated syllable duration, and clear pitch spikes. The delivery sounds like a highly capable teacher giving crucial, high-stakes instructions.
5	Content words are punched with aggressive, intense energy that aggressively forces the listener's attention to specific points. The emphasis pattern is highly percussive, utilizing sharp, forceful bursts of volume to highlight critical concepts. It is a commanding, highly active dynamic structure that bites through the audio mix.
6	The emphasis is applied with violent, explosive intensity, creating massive acoustic disparities between stressed and unstressed words. Highlighted syllables erupt with jarring volume and prolonged duration, resembling a high-pressure sales pitch or a furious argument. The dynamic contrast within the sentence is stretched to its absolute extreme limit.

DFLU · Written source anchors 0–6

Disfluency

Tracks the presence of linguistic noise including fillers, false starts, and self-corrections

Value	Disfluency · `DFLU` · source anchors
0	The audio clip is a pristine, flawless stream of speech with absolutely zero fillers, hesitations, or vocal restarts. It sounds like a perfectly edited studio recording or a masterfully rehearsed script reading. The linguistic signal is completely devoid of any cognitive or mechanical interference.
1	The delivery is highly polished and professional, containing perhaps only a single, negligible micro-hesitation in a long stream of speech. The linguistic output is exceptionally clean, indicating a highly prepared and focused speaker. There is almost no acoustic junk interrupting the primary message.
2	The speech is highly fluent but contains an occasional, organic filler sound that naturally bridges a thought without causing distraction. It represents the smooth, intelligent flow of a highly articulate spontaneous conversation. The tiny acoustic imperfections feel deeply human but do not degrade the legibility.
3	The audio contains a standard, entirely natural amount of non-lexical fillers like 'um' or 'uh', along with minor self-corrections. The delivery feels highly authentic and spontaneous while remaining perfectly easy to comprehend. It represents the exact baseline of unscripted, everyday human processing noise.
4	The speech is noticeably hesitant, with vocal fillers and noticeable processing pauses occurring in nearly every acoustic phrase. The speaker frequently interrupts their own flow to search for words, causing a distinctly staggered and bumpy acoustic output. The high density of linguistic noise significantly slows down the transfer of information.
5	The delivery is overwhelmingly messy, dominated by frequent, distracting restarts, stammers, and heavy usage of vocal fillers. The core message is buried under a thick layer of cognitive interference and broken audio sentences. The listener must actively filter out the high volume of acoustic junk to understand the speaker.
6	The speech is entirely shattered into a chaotic, virtually incoherent web of stammers, abandoned words, and continuous filler sounds. The speaker completely fails to maintain a stable linguistic thread, making it physically difficult to extract any meaning from the audio wave. It is a pure acoustic manifestation of profound cognitive or linguistic breakdown.

STRU · Written source anchors 0–6

Structure

Looks at macro-level organization of ideas within a clip

Value	Structure · `STRU` · source anchors
0	The speech lacks any logical connection between words, phrases, or ideas, presenting as an entirely scattered acoustic word salad. It consists of completely unrelated, jarring outbursts that possess zero macro-level organization. The listener cannot map any linear progression or coherent thought process in the audio.
1	The delivery is incredibly jumpy, with the speaker constantly abandoning topics mid-sentence and pivoting without any acoustic transitions. It is an erratic, highly disorganized stream of audio that totally fails to connect point A to point B. The cognitive map of the speech is fractured and nearly impossible to track.
2	The audio features a very loose, rambling structure where a main idea is heavily buried under layers of irrelevant tangents and side-thoughts. The delivery sounds like an unorganized, wandering stream-of-consciousness that struggles to reach an acoustic destination. The flow is meandering, lacking clear boundaries or logical guideposts.
3	The speech maintains a basic, coherent logical flow that successfully moves from one idea to the next without losing the listener. The speaker utilizes standard conversational markers to link thoughts together in a naturally progressing chain. It is a functional, easily summarizable delivery of audio information.

It is an overwhelming, highly aggressive display of pure interpersonal dominance.

FOCS · Written source anchors 0–6

Focus

Measures the direction of the speaker's interpersonal attention

Reading note: Rate the conveyed stance or affect in context. A voice can perform this quality without establishing the person’s private state.

Value	Focus · `FOCS` · source anchors
0	The acoustic energy is entirely internalized and heavily dissociated, sounding exactly like a person sleep-talking or mumbling strictly to themselves. The speaker demonstrates zero awareness of an external audience, 'dropping' their words aimlessly rather than projecting them outward. It is a profoundly isolated, completely inward-facing vocal geometry.
1	The delivery is completely emotionally detached and highly impersonal, resembling someone coldly reading a script into an empty void. While the voice is technically audible, the 'soul' of the speaker is entirely disconnected from the listener, producing a chillingly distant acoustic profile. There is absolutely zero interpersonal 'reach' in the audio wave.
2	The speaker's attention is clearly split, resulting in a distracted, slightly 'hollow' acoustic delivery where their mind is visibly wandering. They are physically speaking to someone, but the vocal projection lacks true interpersonal grounding, creating a slightly unfocused and floaty audio presence. The communicative intent is weak and continually drifting.
3	The audio captures a standard, polite interactional focus where the speaker is casually aware of the listener without applying intense psychological pressure. The vocal energy is appropriately directed outward, maintaining a comfortable, socially standard interpersonal connection. The acoustic projection is functional, balanced, and appropriately present.
4	The speaker employs clear, highly engaged 'Direct Address,' actively ensuring their acoustic energy firmly lands on the listener.

Value	Perceived Gender · `GEND` · source anchors
0	The acoustic profile features an extremely high fundamental frequency combined with the bright, small-cavity resonance characteristic of a hyper-feminized vocal tract. The voice carries a very light physical weight and delicate harmonic texture, entirely devoid of low-end chest frequencies. It sounds like a high soprano, projecting a bright, purely head-dominant acoustic signature.
1	The audio presents a clearly feminine vocal signature with standard female fundamental pitch ranges and proportionally scaled formant frequencies. The tonal balance is strongly centered in the head and oral cavities, lacking heavy lower-harmonic rumble. The acoustic weight and spectral footprint are unmistakably characteristic of a typical adult woman.
2	The voice is predominantly feminine but exhibits subtle neutral or slightly darkened resonant qualities in its acoustic profile. It operates at a slightly lower fundamental frequency, resembling a female alto or a speaker with a marginally larger perceived vocal tract. The tonal weight is slightly thicker than standard feminine speech, adding a gentle acoustic warmth.
3	The acoustic signature sits perfectly centered on the androgynous spectrum, making it completely ambiguous and difficult to categorize by traditional gender markers. The audio lacks both the sharp, high-frequency brightness of typical feminine speech and the heavy, thick chest rumble of masculine speech. It is a highly balanced, perfectly neutral vocal tract manifestation.
4	The vocal profile is predominantly masculine but features a slightly elevated fundamental pitch and a somewhat smaller resonant cavity than a typical male. The harmonic weight is relatively light, producing a bright, tenor-like acoustic quality that lacks heavy sub-harmonic rumble. It sounds like a youthful male or a man speaking with a noticeably lifted, head-forward resonance.
5	The audio delivers a standard masculine vocal signature characterized by a naturally low fundamental frequency and distinct, robust chest resonance. The spectral balance features strong low-mid frequency support, creating a thick, authoritative acoustic weight. It is the unmistakable, highly resonant sound profile of a typical adult man.
6	The vocal tract produces a hyper-masculinized acoustic profile, heavily dominated by an extremely low fundamental frequency and massive, booming chest resonance. The vocal folds sound incredibly thick, generating an overpowering, low-frequency rumble that fills the entire acoustic space. It mimics the larger-than-life, deeply resonant depth of a cinematic hero or a classic sub-bass radio announcer.

AGEV · Written source anchors 0–6

Voice Age

Tracks the perceived biological age of the speaker based on vocal maturity, elasticity, and wear

Reading note: Describe perceived vocal presentation. This rating does not establish the speaker’s gender identity, sex or actual age; record the listening context and uncertainty.

Value	Voice Age · `AGEV` · source anchors
0	The acoustic signal is dominated by the extremely small vocal tract and unstable, high-pitched fundamental frequency of an infant or toddler. The audio entirely lacks complex linguistic structure, consisting primarily of pure, high-frequency biological resonance and primitive vocalizations. The physical elasticity of the vocal folds produces bright, highly piercing neonatal sound waves.
1	The voice carries the clear, bright, and highly energetic acoustic signature of a pre-pubescent child. The resonant cavity is distinctly small, yet the articulation shows developing structure, producing a lightweight, highly elastic harmonic profile. The audio entirely lacks the grounded, heavy chest frequencies characteristic of adult physical maturity.
2	The vocal profile exhibits the transitional acoustics of an adolescent, blending remnants of childhood brightness with newly developing lower-frequency depth. The fundamental pitch may occasionally destabilize or 'crack,' revealing the rapid biological scaling of the vocal tract. The overall resonance is thickening, but has not yet settled into full adult acoustic weight.
3	The audio showcases a voice at peak biological vigor, producing perfectly elastic, incredibly clean harmonic definition across all frequencies. There is absolutely no acoustic evidence of vocal fatigue, muscular wear, or aging-related texture in the signal. The fundamental pitch is rock-solid, and the resonance is highly resilient, fresh, and perfectly supported.
4	The acoustic signature reflects a fully developed, mature adult, characterized by a highly settled, grounded, and authoritative resonant weight. The vocal folds exhibit a very slight, natural thickening, which adds a warm, robust low-mid frequency presence to the audio. The overall physical support is incredibly stable, projecting a commanding and complete spectral profile.
5	The voice begins to display the distinct acoustic markers of middle-to-late aging, including a slight loss of respiratory support and a narrowing of the functional pitch range. A noticeable 'grainy' or weathered texture permeates the audio, resulting from the natural, slow desiccation of the vocal folds over decades. The physical momentum of the speech is perceptibly heavier and slightly less elastic.
6	The acoustic profile is heavily defined by extreme biological senescence, characterized by a pronounced, uncontrollable physiological tremor or 'wobble' in the fundamental frequency. The resonance sounds highly ossified, thin, and reedy, with significant breathiness indicating a massive loss of muscular vocal support. The audio captures the labored, fragile phonation typical of very advanced age.

0	The speaker's respiratory cycle is completely invisible and inaudible within the acoustic signal, allowing for impossibly long, seamless linguistic phrases. They possess seemingly infinite breath control, characteristic of a highly trained singer or an elite public speaker operating with absolute physiological efficiency. The 'wind' of the lungs never once interrupts the 'music' of the voice.
1	Breathing is strictly controlled and occurs only as highly efficient, barely perceptible micro-inhalations taken at long, calculated intervals. The respiratory function operates entirely in the background of the audio mix, never pulling focus from the acoustic clarity of the words. It is a highly disciplined, remarkably quiet respiratory profile.
2	The audio features standard, completely natural conversational breathing where inhalations occur at logical grammatical pauses. The sound of the breath is mildly audible but entirely unobtrusive, perfectly blending into the organic rhythm of the speech. The respiratory engine sounds healthy, unforced, and entirely typical.
3	The speaker's breathing is noticeably elevated, with inhalations occurring more frequently and audibly than strictly necessary for basic phonation. The slightly heavier air intake suggests a subtle increase in physical engagement, mild psychological stress, or active physical movement. The sound of the respiratory cycle begins to actively assert itself into the audio stream.
4	The respiratory cycle is highly labored, characterized by deep, clearly audible gasps and heavy heaving between sentences. The speaker is rapidly running out of air, forcing them to physically truncate their phrase lengths to accommodate their desperate need for oxygen. The acoustic signal is frequently and aggressively interrupted by the struggle to breathe.
5	The audio is dominated by rapid, highly shallow gasping that violently and unpredictably chops the linguistic stream into fragmented pieces. The speaker sounds heavily winded, as if they have just finished a full-speed sprint or are experiencing severe, acute physical distress. The violent rush of air is almost louder than the actual phonation.
6	The physical ability to speak is almost entirely destroyed by catastrophic respiratory failure, resulting in an agonal, suffocating acoustic profile. The audio captures the terrifying sounds of choking, hyperventilation, or a desperate fight for survival where air cannot be processed into words.

There is absolutely no noticeable constriction in the biological pipeline, allowing the audio to resonate with a highly pleasing, 'open' acoustic geometry. The speech is physically incredibly easy to produce.
2	The voice utilizes standard, neutral conversational muscle tone, applying just enough physical firmness to clearly articulate without squeezing the vocal tract. There is no distracting or uncomfortable physical tension audible in the acoustic signal. The throat remains appropriately relaxed but functionally active.
3	A faint acoustic 'edge' or mild muscular squeeze becomes audible, indicating a subtle tightening of the neck or jaw muscles. This mild tension profile often suggests a speaker who is deeply concentrating, slightly annoyed, or operating under minor psychological stress. The voice loses a fraction of its natural warmth due to this slight physical constriction.
4	The vocal tone sounds noticeably pressed and restricted, as if the audio is being physically pushed through a narrowed, tightly clenched biological pipe. The speaker is clearly carrying heavy stress in their jaw and neck, resulting in a firm, mildly metallic, and highly constrained acoustic signal. The lack of open resonance is physically palpable.
5	The muscles surrounding the vocal folds are heavily strained, producing a hard, grinding, and intensely uncomfortable acoustic texture. The sheer physical effort required to force sound through the tightly constricted throat is blatantly audible, robbing the voice of all organic softness. The audio feels highly stressful and physically painful to listen to.
6	The somatic tension is so extreme that the vocal musculature is entirely rigid and locked, actively crushing the vocal folds and causing the voice to crack or break. The delivery sounds brutally strangled, heavily distorted by the immense external pressure applied by the neck and jaw. It is the acoustic manifestation of a biological system paralyzed by high-stakes stress.

Value	Cognitive Load · `COGL` · source anchors
0	The speech output is perfectly fluid and completely effortless, possessing absolutely zero cognitive hesitation or processing friction. It sounds as though the speaker has completely memorized the text and is reciting it from deep neural pathways without a single micro-second of real-time thought. The thought-to-speech pipeline is flawlessly executed.
1	The cognitive delivery is highly articulate and incredibly fast, demonstrating a near-perfect, highly efficient mental processing speed. The speaker easily translates complex ideas into a perfectly sequenced acoustic stream with almost zero visible mental labor. The intellectual machinery operates with highly impressive, uninterrupted smoothness.
2	The audio features standard, healthy conversational flow where the speaker experiences only occasional, completely natural micro-pauses to search for the correct word. The mental processing is entirely manageable and feels organically easy, creating a comfortable, naturally paced acoustic rhythm. The brain-to-mouth connection is stable and typical.
3	The speaker's real-time mental processing becomes audibly noticeable, creating an uneven acoustic rhythm as they actively build their sentences block by block. There is a distinct 'searching' quality in the voice, accompanied by minor hesitations that reveal the brain working to organize the logic. The cognitive load is elevated but successfully managed.
4	The cognitive machinery is heavily burdened, resulting in a delivery weighed down by frequent vocalized pauses, long gaps, and a distinct acoustic 'heaviness.' The speaker is visibly struggling to formulate their thoughts, heavily slowing down the linguistic output as their brain attempts to solve the communication problem. The mental effort significantly degrades the pacing of the audio.
5	The speaker's mental capacity is severely overloaded, causing them to frequently lose their train of thought, self-correct, and acoustically backtrack. The heavy cognitive friction makes the internal struggle blatantly obvious, heavily fracturing the flow of information and causing the speaker to stumble over their own logic. The brain is clearly failing to keep up with the mouth.
6	The cognitive burden is so catastrophically highâ€”due to extreme shock, complex fabrication, or intellectual overloadâ€”that the speaker's linguistic output completely breaks down. The brain entirely fails to string together a coherent sentence, resulting in a shattered, deeply confused, and logically incoherent acoustic wave. The mental operating system has essentially crashed.

Brightness

Refers to the prominence of high-frequency energy within the voice

Value	Brightness · `BRGT` · source anchors
0	The acoustic signal is completely devoid of high-frequency energy, sounding heavily muffled as if submerged underwater or blocked by a thick physical barrier. Transient consonants and sibilance are entirely absorbed and invisible, leaving only a dark, formless blob of audio. The spectral balance is severely rolled off at the top, resulting in a muddy low-end rumble.
1	The treble frequencies are significantly reduced, creating a woolly, dark acoustic texture that entirely lacks a sharp articulatory edge. Sibilant sounds are soft and heavily suppressed, rendering the vocal signal distinctly dull and top-heavy. While marginally more intelligible than a total high-frequency cutoff, the voice remains heavily veiled and muddy.
2	High-frequency energy is present but gently attenuated, resulting in a warm, rounded, and earthy acoustic profile. This slight treble suppression creates a pleasingly smooth, vintage sound that lacks modern analytical crispness but is exceptionally easy on the ears. Sibilance is naturally controlled and softly absorbed into the frequency mix.
3	The spectral balance represents the perfect, neutral baseline of natural human speech with an entirely even distribution of high and low frequencies. There is a highly functional mix of low-end body and high-end clarity that ensures perfect legibility without harshness. Sibilants and transients hit with standard, unexaggerated acoustic presence.
4	The high frequencies are distinctly well-defined and highly articulate, giving the voice a modern, crisp, and extremely present production quality. Every consonant slices through the audio mix with sharp transient clarity and beautifully distinct sibilance. The acoustic profile feels bright and forward without ever causing auditory fatigue.
5	Treble frequencies are heavily emphasized, adding a brilliant, airy shimmer to the absolute top of the vocal spectrum. The voice sits extremely forward in the mix, characterized by highly pronounced sibilance and a sparkling, ultra-clear acoustic sheen. The continuous high-frequency excitation creates a dazzling, though potentially fatiguing, listening experience.
6	The high-frequency energy is overwhelmingly harsh, resulting in a sharply piercing, sizzling acoustic output that feels physically painful to hear. Sibilant consonants act like breaking glass, dominating the entire spectrum with aggressive, ear-drilling treble spikes.

Roughness

Measures the presence of rapid amplitude modulations or grit within the vocal fold vibration

Value	Roughness · `ROUG` · source anchors
0	The vocal fold vibration is impossibly smooth and pure, closely resembling the clean acoustic geometry of a pure sine wave or a synthetic flute. The signal contains absolutely zero aperiodic noise, biological grit, or vocal fry, resulting in a perfectly clean, uninterrupted tonal stream. It is a flawless, glassy acoustic emission completely free of organic friction.
1	Phonation is exceptionally consistent and velvety, exhibiting only the absolute faintest microscopic traces of organic human texture. The vocal folds vibrate with incredibly healthy, polished regularity, generating a highly soothing and buttery acoustic output. The sound wave glides effortlessly with almost zero internal biological friction.
2	The voice features the standard, healthy level of organic texture typical of everyday human speech and natural biology. A slight, highly natural acoustic 'bite' prevents the tone from sounding synthetic, rooting the vocal production in grounded human reality. There is no distracting grit, fry, or harshness present in the highly stable signal.
3	A distinct, grainy texture noticeably permeates the vocal tone, introducing rapid amplitude modulations into the fundamental frequency. The voice sounds as though it contains a layer of acoustic sand, typical of mild vocal fry or slightly desiccated vocal folds. This gentle grit adds a rough, tactile characteristic to the otherwise stable phonation.
4	The acoustic signal is heavily raspy and scratchy, revealing a highly weathered biological apparatus operating with significant internal friction. The vocal folds vibrate with a continuous, grinding noise floor, sounding like a speaker with a mild cold or a long-term smoking habit. This heavy grit is an inescapable, defining feature of the overall sonic footprint.
5	The vocal texture is aggressively harsh and distinctly growling, driven by intense physical friction and heavy aperiodic interference at the vocal folds. The fundamental tone is deeply disrupted by a heavy, rattling rumble that heavily distorts the biological sound wave. It is a highly abrasive, physically forceful acoustic grind that dominates the spectrum.
6	The fundamental tone is almost completely obliterated by violent, aperiodic noise and extreme biological crunch. The vocal folds are in a state of chaotic, shredding friction, producing an acoustic output akin to a death-metal growl or severe physical tissue breakdown. It is a jarring, maximally rough audio signal utterly devoid of clean periodicity.

HARM · Written source anchors 0–6

Harmonicity

Measures the ratio of periodic signal to aperiodic noise

Value	Harmonicity · `HARM` · source anchors
0	The acoustic signal is entirely composed of broadband aperiodic noise, lacking even the absolute faintest trace of a discernible fundamental pitch. It represents a totally unvoiced, absolute whisper where all acoustic energy is derived from air turbulence rather than vocal fold vibration. The sound wave is a ghost made purely of friction and white-noise static.
1	A microscopic, ghostly hint of fundamental pitch barely survives inside a dense, overwhelming cloud of high-frequency white noise. The acoustic output is primarily breath and air leakage, with only a tiny, highly fragile fraction of energy successfully converted into tonal resonance. It sounds like a heavy, desperate whisper struggling to find its voice.
2	The audio is distinctly breathy, featuring a clear fundamental pitch that is continuously wrapped in a thick, highly audible layer of air turbulence. Known psychoacoustically as 'bedroom voice,' the vocal folds fail to close completely, allowing a steady stream of hissing noise to mix with the tone. The resulting sound is highly soft, deeply diffused, and highly aerated.
3	The signal achieves the standard, healthy ratio of periodic tone to aperiodic noise characteristic of normal human speaking voices. The fundamental pitch is solid and highly clear, acting as the primary acoustic carrier while only a negligible, natural amount of breath noise escapes. The vocal fold closure is biologically balanced and perfectly functional.
4	The voice is highly resonant and exceptionally focused, featuring a massive fundamental pitch and a remarkably low acoustic noise floor. The tonal energy is highly efficient and distinctly ringing, characteristic of a highly trained public speaker maximizing their vocal fold closure. The audio wave is deeply concentrated and musically tunable.
5	The acoustic output is exceptionally tonal and brilliantly bell-like, successfully converting virtually all breath energy into a pure, ringing fundamental frequency. There is absolutely no audible air leakage or turbulent hiss, resulting in an incredibly clean, almost musical vocal tone. The harmonic stack is incredibly rich, highly stable, and mathematically beautiful.
6	The harmonicity is so absolute and mathematically perfect that the voice sounds entirely computer-generated or digitally synthesized. It is completely devoid of the organic 'fuzz', breath, or aperiodic noise inherently attached to human biology. The resulting tone is a sterile, digitally pure acoustic ideal that feels entirely artificial.

The resulting audio is highly narrow, severely small, and distinctly boxed-in, perfectly mirroring the heavy frequency compression of a low-quality telephone call. The signal lacks both warmth and brilliance, feeling highly confined.
2	The vocal profile is highly intelligible and clear but remains distinctly slender and physically lightweight in its overall spectral footprint. It lacks the rich low-mid body required to actively command the acoustic space, feeling functionally present but physically very small. The voice does not push significant air or project heavy acoustic mass.
3	The audio features a solid, naturally healthy spectral bandwidth that feels organically complete and appropriately sized for a human speaker. It perfectly balances enough low-mid energy to sound grounded with enough high-end to sound distinctly realistic and present. The acoustic volume occupies a standard, highly comfortable amount of space.
4	The vocal signal is incredibly rich and highly wide, spreading out across a broad frequency spectrum to create a highly expensive acoustic texture. It possesses a strong, thick physical body that feels highly present and structurally robust in the audio mix. The resulting sound wave occupies a massive amount of highly pleasing sonic territory.
5	The audio footprint is massive, physically thick, and highly commanding, featuring a heavily reinforced spectral body that projects immense power. The voice sounds perfectly captured by a high-end studio microphone, fully utilizing a deep proximity effect to generate a heavy, weighty acoustic mass. It effortlessly and entirely dominates the low and mid-frequency ranges.
6	The vocal fullness reaches an overwhelming, IMAX-level cinematic scale, completely saturating the entire acoustic field with unbelievable depth and width. The sound is astronomically big, creating a highly exaggerated, rumbling voiceover effect that vibrates deep within the listener's physical chest. It is a hyper-saturated, omnipresent wall of spectral density.

Reading note: Warmth here is acoustic timbre, especially the low-mid-frequency balance. It does not mean interpersonal kindness or affection.

Value	Warmth · `WARM` · source anchors
0	The acoustic profile is entirely devoid of low-mid frequency resonance, resulting in a distinctly cold, metallic, and surgically sterile sound. The voice completely lacks any organic 'cuddle' or bodily depth, sounding like a harsh dental drill or a highly detached, emotionless machine. It is an actively uninviting, heavily rigid sonic texture.
1	The audio is distinctly tinny and highly top-heavy, severely lacking the low-mid bodily warmth required to sound natural or comforting. This heavily skewed frequency response creates a cheap, highly hollow, and distinctly irritating acoustic signature. The voice feels entirely disconnected from the physical warmth of the human chest.
2	The vocal resonance is highly functional but distinctly neutral-cool, operating with a very dry acoustic profile that prioritizes hard information over comfort. The low-mid frequencies are present but distinctly suppressed, preventing the voice from sounding naturally inviting or physically relaxed. It is a highly utilitarian, slightly stiff acoustic delivery.
3	The resonance perfectly strikes the standard human baseline, offering a highly balanced, universally comfortable acoustic profile. There is exactly enough low-mid frequency presence to sound biologically grounded and human, but not so much that the audio becomes muddy or muffled. The natural warmth of the chest and throat is perfectly proportioned.
4	The voice exhibits a highly pleasant, distinctly woody, and cozy resonance heavily supported by a smooth, gentle low-mid frequency emphasis. This targeted boost in the lower harmonics creates a deeply soothing, physically close acoustic sensation that feels instantly comfortable to the listener. The sonic texture is round, inviting, and inherently relaxing.
5	High levels of rich, low-mid resonance heavily saturate the audio, creating a deeply velvety, highly attractive 'late-night radio DJ (disc jockey)' acoustic profile. The vocal folds produce a heavy, exceptionally warm hum that perfectly rounds off all harsh transients and fills the sonic space with comfortable depth. It is a highly engineered, deeply attractive resonant glow.
6	The warmth is so overwhelmingly massive that the voice essentially melts into a gigantic, enveloping physical hug of pure low-frequency resonance. It is a completely bass-heavy, hyper-cozy, 'chocolate-like' acoustic environment that completely swallows the listener's ears. The sound wave entirely sacrifices sharp intelligibility in favor of absolute, overwhelming sonic comfort.

The audio profile is the absolute, unyielding antithesis of a metallic machine.
1	The acoustic output is deeply grounded in a soft, earthy resonance with only the absolute minimal, microscopic trace of any metallic ping. The sound wave is highly natural, prioritizing a warm, fleshy biological dampening over hard, reflective acoustic amplification. The voice feels intimately human and completely devoid of artificial stiffness.
2	The audio features a standard, highly typical human resonance containing only a negligible, entirely organic amount of high-frequency acoustic 'ping.' The biological vocal tract functions normally, beautifully balancing soft tissue absorption with the hard reflection of the hard palate. The overall sonic footprint remains firmly and functionally natural.
3	A distinct firmness begins to visibly infiltrate the acoustic profile, giving the voice a stiff, slightly 'hard' physical quality. The speaker sounds as though they are operating with a tightly clenched jaw, causing higher frequencies to reflect harshly off the internal vocal tract. This introduces a subtle but completely un-ignorable metallic sheen.
4	The audio is deeply characterized by a clear, highly audible metallic resonance that sounds exactly like a voice bouncing directly off a steel plate. A pronounced, highly inharmonic 'ring' or 'ping' actively interferes with the fundamental tone, highly typical of extreme vocal tension or aggressive projection. The sound wave feels intensely rigid and unyielding.
5	The vocal output is fiercely clanging and distinctly piercing, heavily saturated with sharp, iron-like inharmonic frequencies that actively assault the ear. The resonance is incredibly hard and physically dangerous, completely stripping away any illusion of soft, organic biological tissue. The acoustic edge is highly cold, severely abrasive, and deeply metallic.
6	The voice is entirely consumed by a pure, robotic metallic resonance, sounding exactly like a synthetic machine or a heavily armored entity. It is a violently hard, continuously clanging acoustic signal that lacks even a single trace of organic, human softness. The sonic texture is a perfect, terrifying manifestation of cold, vibrating steel.

The speech starts rushed and compressed, then steadily loses all forward momentum as syllables stretch wider and wider apart. The speed differential from start to finish is extreme, covering the full range from 1.5x to 0.5x normal pace.
1	The speech begins at a clearly elevated pace and undergoes a heavy, sustained deceleration across the full duration. The initial brisk delivery gradually and obviously slows down, with the speaker audibly losing rhythmic momentum as the phrase progresses. The tempo drops from roughly 1.3x to 0.7x normal speed, creating a pronounced but not extreme winding-down effect.
2	The temporal dynamics exhibit a subtle, natural easing of the tempo, starting slightly faster than normal and gently braking to a slightly slower pace by the end. This mild deceleration functions as a deliberate, comfortable cadence, carefully reducing momentum from about 1.1x to 0.9x normal speed. The slowdown is controlled and rhythmically satisfying, like a speaker naturally winding down a thought.
3	The velocity of the speech remains absolutely locked and perfectly steady from the very first syllable to the last. There is exactly zero detectable acceleration or deceleration, resulting in a strictly linear, metronomic temporal delivery. The acoustic momentum is held at a completely constant speed throughout the entire clip.
4	The speech trajectory features a subtle, natural forward lean, beginning slightly slower than normal and gently pushing the tempo faster as the phrase concludes. This mild acceleration from about 0.9x to 1.1x normal speed suggests a rising tide of engagement or growing confidence. The acoustic momentum subtly builds, creating a gently forward-moving vector.
5	The audio begins at a noticeably slow, deliberate pace and captures a clear, sustained acceleration across the full duration, with the speaker audibly speeding up from roughly 0.7x to 1.3x normal speed. The acoustic rhythm compresses progressively as the phrase progresses, driven by an escalating surge of energy or urgency. The temporal vector is distinctly forward-thrusting with an obvious speed buildup.
6	The tempo vector begins extremely slowly, with syllables heavily stretched and drawn out, before undergoing a massive, continuous acceleration that ends at a rapid, high-energy pace. The speech transforms from a crawl at 0.5x to a rush at 1.5x normal speed, with the acoustic momentum building relentlessly throughout. The speed differential from start to finish is extreme, the mirror image of bucket 0.

DARC · Written source anchors 0–6

Dynamic Arc

Measures the trajectory of loudness across the clip

Value	Dynamic Arc · `DARC` · source anchors
0	The acoustic volume begins at a highly audible level before suffering a total, catastrophic collapse, fading away into absolute dead silence. The audio completely dissolves and dies out, perfectly tracking a highly linear trajectory toward complete acoustic nothingness. The volume envelope is a pure, absolutely unrecoverable fade to black.
1	The speech vector is characterized by a clear, incredibly steady, and highly pronounced diminuendo that drops the volume drastically across the clip. The speaker sounds exactly as if they are rapidly losing all conviction or physically backing away from the microphone mid-sentence. The dynamic envelope heavily deflates, bleeding massive acoustic energy continuously.
2	The volume trajectory features a gentle, highly natural softening of acoustic power at the very end of the linguistic phrase. This minor dip in decibels is a standard, deeply organic human cadence used to gently signal the conclusion of a thought. The dynamic envelope 'lands' smoothly and softly without entirely losing its structural integrity.
3	The decibel level remains absolutely flatlined, exhibiting exactly zero change in audio volume from the beginning to the very end of the clip. The dynamic range is perfectly compressed and highly static, flawlessly maintaining an unwavering, mathematically constant acoustic output. The volume envelope is entirely frozen in place.
4	The dynamic envelope perfectly traces a highly controlled, deeply satisfying bell curve of rising and falling acoustic volume. The speech begins quietly, smoothly swells into a louder, highly energetic peak in the middle, and then gracefully softens back down at the end. It is a deeply musical, highly planned trajectory of deliberate vocal power.
5	The volume vector tracks a clear, highly aggressive crescendo, building massive acoustic loudness and physical insistence across the duration of the clip. The speaker is actively 'powering up,' visibly driving the decibel level significantly higher with every passing word. The dynamic envelope is highly ascendant, continuously gathering forceful, undeniable momentum.
6	The dynamic arc covers an impossibly extreme range, starting as a tiny, barely audible whisper and exploding directly into a massive, floor-shaking scream. This violent trajectory acts as a sheer vertical ramp of acoustic power, completely shattering the initial quiet with an overwhelming surge of volume. The decibel differential is absolutely massive and highly shocking.

ARSH · Written source anchors 0–6

Arousal Shift

Measures the change in physiological activation over the duration of the clip

Value	Arousal Shift · `ARSH` · source anchors
0	The physiological trajectory begins in a state of high activation before entirely collapsing into a near-comatose, heavily sedated acoustic state. The speaker's biological engine suffers a total loss of vitality, perfectly mirroring a person passing out or entirely surrendering to absolute exhaustion. The energy vector is a catastrophic, completely unrecoverable downward plunge.
1	The audio tracks a highly significant de-escalation of autonomic nervous system energy, moving rapidly from high alert down to a state of deep, relative calm. This deep drop in physical intensity perfectly mimics a massive 'sigh of relief' or the immediate, breathless aftermath of a resolved conflict. The acoustic engine spins down aggressively and audibly.
2	The physiological vector exhibits a subtle, highly comforting settling of bodily tension as the audio smoothly progresses to its end. The vocal energy softens and relaxes slightly towards the final words, clearly suggesting the speaker is becoming physically more comfortable or gently tired. The acoustic momentum gently decelerates into a highly relaxed bodily posture.
3	The autonomic activation level remains entirely static and completely constant, demonstrating exactly zero change in baseline physiological arousal. The exact energy level at the start of the clip is perfectly mirrored at the end, firmly locking the speaker into an unyielding physical state. The biological engine neither revs up nor physically spins down.
4	The speech trajectory tracks a subtle, highly engaging 'perking up' of physiological alertness and rising bodily energy. The speaker sounds perceptibly more awake, highly interested, and physically engaged by the end of the phrase than they did at the exact beginning. The acoustic engine gently revs up, applying a light, highly active forward-moving pressure.
5	The energy vector traces a clear, highly driving, and intensely aggressive escalation of physical intensity and massive autonomic arousal. The vocal folds are pushed significantly harder, louder, and faster as the speaker actively works themselves up into a heightened state of severe excitement or anger. The biological engine rapidly accelerates toward an explosive boiling point.
6	The physiological trajectory is a completely violent, 0-to-100 explosion of extreme autonomic mobilization that fundamentally shatters the acoustic baseline. The clip begins in a state of calm and literally detonates into a full scream, shout, or full-blown panic attack within seconds. The energy vector is a highly terrifying, totally combustible biological acceleration.
