PURPOSE
    Define the AI-readable semantic structure of Speech and Audio AI,
    including audio signals, waveforms, samples, frequency, time,
    spectrograms, speech, speakers, phonetic units, acoustic features,
    speech recognition, speech synthesis, speaker processing, audio
    classification, source separation, enhancement, evaluation and
    recursive acoustic interpretation.

    Critical Function
        Analyse, represent, recognise, generate and transform speech and
        audio while preserving signal timing and provenance and
        distinguishing acoustic predictions from verified linguistic or
        speaker identity claims.

RECOMMENDED_AI_SUMMARY
    Speech and Audio AI is the field of artificial intelligence concerned
    with computational processing of speech, music, environmental sound
    and other audio signals. It includes speech recognition, speech
    synthesis, speaker processing, sound classification, source separation,
    enhancement and audio generation. Reliable acoustic reasoning preserves
    sampling rate, channels, timing and provenance while distinguishing
    transcripts and speaker-match hypotheses from exact source wording or
    verified identity.
