# Whisper Small fine-tuned on WAXAL — Ikposo
|
| 20 |
|
| 21 |
+
This model is part of **[WAXALNet](https://huggingface.co/waxal-benchmarking)**, a suite of ASR models fine-tuned on the [WAXAL corpus](https://huggingface.co/waxal-benchmarking) across 19 African languages, developed as part of the WAXAL ASR Benchmark study.
|
|
|
|
| 22 |
|
| 23 |
+
## Model Details
|
| 24 |
|
| 25 |
+
| | |
|
| 26 |
+
|---|---|
|
| 27 |
+
| **Language** | Ikposo (`kpo`) |
|
| 28 |
+
| **Language Family** | Niger-Congo (Kwa) |
|
| 29 |
+
| **Architecture** | Whisper Small (244M parameters) |
|
| 30 |
+
| **Base Model** | [openai/whisper-small](https://huggingface.co/openai/whisper-small) |
|
| 31 |
+
| **Training Data** | WAXAL corpus (conversational spontaneous speech) |
|
| 32 |
+
| **Test WER** | 77.5% |
|
| 33 |
+
| **Test CER** | 26.5% |
|
| 34 |
+
| **License** | apache-2.0 |
|
| 35 |
|
| 36 |
+
## Intended Use
|
| 37 |
|
| 38 |
+
This model is intended for automatic speech recognition of **Ikposo** conversational speech. It was evaluated on the WAXAL test set (spontaneous, image-prompted speech) and partially on FLEURS (read speech). It is suitable for research and low-resource ASR applications. It is not recommended for high-stakes production use without further validation.
|
| 39 |
|
| 40 |
+
## Training Data
|
| 41 |
|
| 42 |
+
Fine-tuned on the [WAXAL corpus](https://huggingface.co/waxal-benchmarking), a large-scale dataset of transcribed, image-prompted spontaneous speech across 19 African languages recorded in participants' natural environments. The Ikposo training split contains conversational speech across diverse speakers. Data is released under CC-BY 4.0.
|
| 43 |
|
| 44 |
+
## Usage
|
| 45 |
|
| 46 |
+
```python
|
| 47 |
+
from transformers import pipeline
|
| 48 |
+
|
| 49 |
+
asr = pipeline("automatic-speech-recognition",
|
| 50 |
+
model="waxal-benchmarking/whisper-small-waxal-kpo")
|
| 51 |
+
result = asr("audio.wav")
|
| 52 |
+
print(result["text"])
|
| 53 |
+
```
|
| 54 |
+
|
| 55 |
+
## Test Set Performance (WAXAL Benchmark)
|
| 56 |
+
|
| 57 |
+
Evaluated on the filtered WAXAL test set (duration >= 1.5s, speech rate >= 4 WPS).
|
