## Metrics

| Metric | Value |
|--------|-------|
| `wer` | 0.4231 |
| `cer` | 0.1618 |


## Training data

- `google/WaxalNLP (aka_asr)`
- `fsicoli/common_voice_22_0 (tw)`
- `fsicoli/common_voice_22_0 (en)`
- `ghananlpcommunity/twi-speech-text-multispeaker-16k (default)`


## Intended use

- In-product ASR / TTS / chat for Twi (Akan) and English health conversations in Ghana.
- Research on low-resource Ghanaian language speech and health dialogue.

## Out of scope

- Clinical diagnosis or autonomous medical decisions.
- Claiming near-native quality without reporting held-out WER/CER or human A/B scores.

## How to load

```python
from transformers import pipeline  # or AutoModel + processor per task
# repo: teckedd/gha-whisper-small-twi-en-balanced-v7-lite
