| # UGAkan-ImpairedSpeechData (Research Working Copy) |
|
|
| Personal working copy for ASR research. |
| Original dataset: **UGAkan-ImpairedSpeechData** (University of Ghana). |
|
|
| ## 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) |
