# whisper-medium-it-multi

Fine-tuned [openai/whisper-medium](https://huggingface.co/openai/whisper-medium) (769M params) for Italian ASR on multiple datasets.

**Author:** Ettore Di Giacinto

Brought to you by the [LocalAI](https://github.com/mudler/LocalAI) team. This model can be used directly with [LocalAI](https://localai.io).

## Usage with LocalAI

This model is ready to use with [LocalAI](https://localai.io) via the `whisperx` backend.

Save the following as `whisperx-medium-it-multi.yaml` in your LocalAI models directory:

```yaml
name: whisperx-medium-it-multi
backend: whisperx
known_usecases:
  - transcript
parameters:
  model: LocalAI-io/whisper-medium-it-multi-ct2-int8
  language: it
```

Then transcribe audio via the OpenAI-compatible endpoint:

```bash
curl http://localhost:8080/v1/audio/transcriptions \
  -H "Content-Type: multipart/form-data" \
  -F file="@audio.mp3" \
  -F model="whisperx-medium-it-multi"
```

## Results

Evaluated on combined test set (Common Voice + MLS + VoxPopuli):

| Step | WER |
|------|-----|
| 1000 | 17.55% |
| 3000 | 16.71% |
| 5000 | 14.00% |
| 7000 | 13.02% |
| 9000 | 12.10% |
| 10000 | **12.37%** |
