# whisper large-v2 fine-tuned on CommonVoice Persian

This repository provides all the necessary tools to perform automatic speech
recognition from an end-to-end whisper model fine-tuned on CommonVoice (Persian Language) within
SpeechBrain. For a better experience, we encourage you to learn more about
[SpeechBrain](https://speechbrain.github.io).

The performance of the model is the following:

| Release | Test CER | Test WER | GPUs |
|:-------------:|:--------------:|:--------------:| :--------:|
| 01-02-23 | 9.38 |  31.75 | 1xV100 16GB |

## Pipeline description

This ASR system is composed of whisper encoder-decoder blocks:
- The pretrained whisper-large-v2 encoder is frozen.
- The pretrained Whisper tokenizer is used.
- A pretrained Whisper-large-v2 decoder ([openai/whisper-large-v2](https://huggingface.co/openai/whisper-large-v2)) is finetuned on CommonVoice Fa.
The obtained final acoustic representation is given to the greedy decoder. 

The system is trained with recordings sampled at 16kHz (single channel).
The code will automatically normalize your audio (i.e., resampling + mono channel selection) when calling *transcribe_file* if needed.

## Install SpeechBrain

First of all, please install tranformers and SpeechBrain with the following command:

```
pip install speechbrain transformers
```

Please notice that we encourage you to read our tutorials and learn more about
[SpeechBrain](https://speechbrain.github.io).

### Transcribing your own audio files (in Persian)

```python

from speechbrain.pretrained import WhisperASR

asr_model = WhisperASR.from_hparams(source="speechbrain/asr-whisper-large-v2-commonvoice-fa", savedir="retrained_models/asr-whisper-large-v2-commonvoice-fa")
asr_model.transcribe_file("speechbrain/asr-whisper-large-v2-commonvoice-ar/example-fa.mp3")


```
### Inference on GPU
To perform inference on the GPU, add  `run_opts={"device":"cuda"}`  when calling the `from_hparams` method.

### Training
The model was trained with SpeechBrain.
To train it from scratch follow these steps:
1. Clone SpeechBrain:
```bash
git clone https://github.com/speechbrain/speechbrain/
```
2. Install it:
```bash
cd speechbrain
pip install -r requirements.txt
pip install -e .
```

3. Run Training:
```bash
cd recipes/CommonVoice/ASR/transformer/
python train_with_whisper.py hparams/train_fa_hf_whisper.yaml --data_folder=your_data_folder
```

You can find our training results (models, logs, etc) [here](https://drive.google.com/drive/folders/1nzMMYmB5SxMKsFUk-rM9_ijcqzia8pX7).

### Limitations
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.
