    comments:
    - Audio event segment for speech, music, silence, sound event detection
    - Temporal boundaries with start/end seconds (primary) and ISO 8601 (secondary)
    - Confidence scoring for AI-generated detections
    - Part of Rule 53 slot migration from audio_event_segments
    - Audio types: SPEECH, MUSIC, SILENCE, SOUND_EVENT, NOISE, MIXED
    - 'Preserved from prior description: Temporal segment of audio containing a detected audio event. Represents a bounded temporal portion of audio content where a specific type of audio event has been detected, including speech segments, music, silence, sound events, and noise segments.'
