wav2vec 2.0 with CTC/Attention trained on CommonVoice French (No LM)

This repository provides all the necessary tools to perform automatic speech recognition from an end-to-end system pretrained on CommonVoice (French Language) within SpeechBrain. For a better experience, we encourage you to learn more about SpeechBrain.

The performance of the model is the following:

Pipeline description

This ASR system is composed of 2 different but linked blocks:

  • Tokenizer (unigram) that transforms words into subword units and trained with the train transcriptions (train.tsv) of CommonVoice (FR).
  • Acoustic model (wav2vec2.0 + CTC/Attention). A pretrained wav2vec 2.0 model (LeBenchmark/wav2vec2-FR-M-large) is combined with two DNN layers and finetuned on CommonVoice FR. The obtained final acoustic representation is given to the CTC and attention decoders.

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.

Transcribing your own audio files (in French) 

from speechbrain.pretrained import EncoderDecoderASR

asr_model = EncoderDecoderASR.from_hparams(source="speechbrain/asr-wav2vec2-commonvoice-fr", savedir="pretrained_models/asr-crdnn-commonvoice-fr")
asr_model.transcribe_file("example-fr.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:

  1. Clone SpeechBrain:
git clone https://github.com/speechbrain/speechbrain/
  1. Install it:
cd speechbrain
pip install -r requirements.txt
pip install -e .
  1. Run Training:
cd recipes/CommonVoice/ASR/seq2seq
python train_with_wav2vec.py hparams/train_fr_with_wav2vec.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.
