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.

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) 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==4.28.0

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Transcribing your own audio files (in Persian)

python

from speechbrain.inference.ASR import WhisperASR

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

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:

Clone SpeechBrain:

git clone https://github.com/speechbrain/speechbrain/

Install it:

bash

cd speechbrain
pip install -r requirements.txt
pip install -e .

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.

Limitations

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