Structure on this repo
Metadata Columns
| Column | Description |
|---|---|
| filename | Audio filename |
| aetiology | Raw aetiology label |
| aetiology_key | Normalised key |
| gender | Speaker gender |
| speaker_id | Unique speaker ID |
| environment | Recording environment |
| transcription | Akan transcription |
| duration | Audio duration in seconds |
| severity | Severity label |
| audio_path | Original Drive path |
| split_unified | train / val / test_clean / test_hard |
| split_aetiology | Per-aetiology split for cross-generalization |
Split Strategy
- Split by speaker ID — no leakage
- Unified: 70% train / 10% val / 10% test_clean / 10% test_hard
- Per-aetiology: separate splits for cross-generalization experiments
- Stroke = zero-shot test condition (male only)
