# CRDNN 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](https://speechbrain.github.io). The given ASR model performance are: |

## Pipeline description |
|
|
|
This ASR system is composed of 2 different but linked blocks: |
|
1. Tokenizer (unigram) that transforms words into subword units and trained with |
|
the train transcriptions (train.tsv) of CommonVoice (FR). |
|
3. Acoustic model (CRDNN + CTC/Attention). The CRDNN architecture is made of |
|
N blocks of convolutional neural networks with normalization and pooling on the |
|
frequency domain. Then, a bidirectional LSTM is connected to a final DNN to obtain |
|
the final acoustic representation that is given to the CTC and attention decoders. |

## Install SpeechBrain |
|
|
|
First of all, please install SpeechBrain with the following command: |
|
|
|
``` |
|
pip install speechbrain |
|
``` |
|
|
|
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 French) |
|
|
|
```python |
|
from speechbrain.pretrained import EncoderDecoderASR |
|
|
|
asr_model = EncoderDecoderASR.from_hparams(source="speechbrain/asr-crdnn-commonvoice-fr", savedir="pretrained_models/asr-crdnn-commonvoice-fr") |
|
asr_model.transcribe_file("speechbrain/asr-crdnn-commonvoice-fr/example-fr.wav") |
|
|
|
``` |
|
|
|
### Inference on GPU |
|
To perform inference on the GPU, add `run_opts={"device":"cuda"}` when calling the `from_hparams` method. |
|
|
|
### Limitations |
|
The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets. |
