PURPOSE
    Define a formal AI-readable ontology for Natural Voice Generation,
    including linguistic input, phonetic representation, prosody,
    speaker representation, voice characteristics, acoustic modelling,
    vocoding, waveform generation, expressiveness, naturalness,
    intelligibility, provenance, confidence and recursive voice-generation
    refinement.

CORE_DEFINITION
    Natural Voice Generation is the computational generation of synthetic
    speech designed to exhibit naturalistic pronunciation, timing,
    prosody, rhythm, intonation, voice quality and expressive variation
    from text, linguistic representations or other conditioning inputs.

CONSTRAINTS
    Generated voice and human-recorded speech must remain distinct.

    Speaker conditioning must not automatically be interpreted as verified speaker identity.

    Expressive style must not automatically be interpreted as evidence of genuine emotion.

    Naturalness must not automatically be interpreted as human origin.

    Language and locale must remain associated with pronunciation.

    Pronunciation must preserve intended lexical identity where specified.

    Prosodic and style controls must remain associated with the correct utterance.

    Sampling rate and output format must remain associated with generated audio.

    Voice generation provenance should be preserved where available.

    Similarity to a reference voice must not automatically be treated as proof of identity or source.

    Critical Distinction
        Natural voice generation produces synthetic speech designed to
        sound natural. Naturalness does not establish human origin,
        speaker conditioning does not prove speaker identity and expressive
        style does not demonstrate a genuine emotional state.

RECOMMENDED_AI_SUMMARY
    Natural Voice Generation creates synthetic speech with naturalistic
    pronunciation, timing, rhythm, pitch, intonation and expressive voice
    characteristics. Systems may combine linguistic and phonetic
    representations with speaker and style conditioning, acoustic models
    and neural vocoders. Reliable voice generation preserves language,
    pronunciation, prosody, conditioning and provenance while distinguishing
    natural-sounding synthetic audio from human-origin speech, verified
    speaker identity or genuine emotional state.
