|
|
|
**DEFINITION**:
|
|
|
|
|
|
AudioEventSegment represents a bounded temporal portion of audio content
|
|
|
|
where a specific type of audio event has been detected. This includes:
|
|
|
|
- Speech segments (with optional speaker/language info)
|
|
|
|
- Music segments (with optional genre/type info)
|
|
|
|
- Silence segments (gaps between audio)
|
|
|
|
- Sound event segments (applause, laughter, ambient sounds)
|
|
|
|
- Noise segments (for quality assessment)
|
|
|
|
|
|
**RELATIONSHIP TO VideoTimeSegment**:
|
|
|
|
|
|
AudioEventSegment is a specialized sibling of VideoTimeSegment:
|
|
|
|
- Both extend CIDOC-CRM E52_Time-Span concept
|
|
|
|
- VideoTimeSegment: general video temporal segments
|
|
|
|
- AudioEventSegment: audio-specific event segments
|
|
|
|
|
|
**AUDIO EVENT TYPES**:
|
|
|
|
|
|
| Event Type | Description | Example |
|
|
|
|
|------------|-------------|---------|
|
|
|
|
| SPEECH | Human speech detected | Interview segment |
|
|
|
|
| MUSIC | Music detected | Background soundtrack |
|
|
|
|
| SILENCE | Very low or no audio | Gap between segments |
|
|
|
|
| SOUND_EVENT | Non-speech/music sounds | Applause, footsteps |
|
|
|
|
| NOISE | Noise/interference | Quality issue marker |
|
|
|
|
| MIXED | Multiple event types | Overlapping audio |
|
|
|
|
|
|
**HERITAGE USE CASES**:
|
|
|
|
|
|
| Content Type | Application |
|
|
|
|
|--------------|-------------|
|
|
|
|
| Oral histories | Speech segment identification |
|
|
|
|
| Virtual tours | Background music detection |
|
|
|
|
| Lecture recordings | Audience reaction segments |
|
|
|
|
| Conservation videos | Narration vs ambient sound |
|
|
|
|
| Archival footage | Audio quality assessment |
|
|
|
|
|
|
**PROVENANCE**:
|
|
|
|
|
|
Created as part of slot migration (Rule 53) from deprecated
|
|
|
|
`audio_event_segments` slot to generic `has_segment` pattern.
