|
|
This repository provides all the necessary tools to perform enhancement and |
|
robust ASR training (EN) within |
|
SpeechBrain. For a better experience we encourage you to learn more about |
|
[SpeechBrain](https://speechbrain.github.io). The model performance is: |

## Pipeline description |
|
|
|
The mimic loss training system consists of three steps: |
|
|
|
1. A perceptual model is pre-trained on clean speech features, the |
|
same type used for the enhancement masking system. |
|
2. An enhancement model is trained with mimic loss, using the |
|
pre-trained perceptual model. |
|
3. A large ASR model pre-trained on LibriSpeech is fine-tuned |
|
using the enhancement front-end. |
|
|
|
The enhancement and ASR models can be used together or |
|
independently. |
|
|
|
## 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). |
|
|
|
## Pretrained Usage |
|
|
|
To use the mimic-loss-trained model for enhancement, use the following simple code: |
|
|
|
```python |
|
import torchaudio |
|
from speechbrain.pretrained import SpectralMaskEnhancement |
|
|
|
enhance_model = SpectralMaskEnhancement.from_hparams( |
|
source="speechbrain/mtl-mimic-voicebank", |
|
savedir="pretrained_models/mtl-mimic-voicebank", |
|
) |
|
enhanced = enhance_model.enhance_file("speechbrain/mtl-mimic-voicebank/example.wav") |
|
|
|
# Saving enhanced signal on disk |
|
torchaudio.save('enhanced.wav', enhanced.unsqueeze(0).cpu(), 16000) |
|
``` |
|
### 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 (150e1890). |
|
To train it from scratch follows these steps: |
|
1. Clone SpeechBrain: |
|
```bash |
|
git clone https://github.com/speechbrain/speechbrain/ |
|
``` |
|
2. Install it: |
|
``` |
|
cd speechbrain |
|
pip install -r requirements.txt |
|
pip install -e . |
|
``` |
|
|
|
3. Run Training: |
|
``` |
|
cd recipes/Voicebank/MTL/ASR_enhance |
|
python train.py hparams/enhance_mimic.yaml --data_folder=your_data_folder |
|
``` |
|
|
|

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