# Neural SI-SNR Estimator
This repository provides the SI-SNR estimator model introduced for the REAL-M dataset.
| Release | Test-Set (WHAMR!) average l1 error |
|:---:|:---:|
| 18-10-21 | 1.7 dB |
## 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).
### Minimal example for SI-SNR estimation
```python
from speechbrain.pretrained import SepformerSeparation as separator
from speechbrain.pretrained.interfaces import SNREstimator as snrest
import torchaudio
model = separator.from_hparams(source="speechbrain/sepformer-whamr", savedir='pretrained_models/sepformer-whamr2')
est_sources = model.separate_file(path='speechbrain/sepformer-wsj02mix/test_mixture.wav')
snr_est_model = snrest.from_hparams(source="speechbrain/REAL-M-sisnr-estimator-main")
mix, fs = torchaudio.load('test_mixture.wav')
snrhat = snr_est_model.estimate_batch(mix, est_sources)
```
### 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 (fc2eabb7).
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/REAL-M/sisnr-estimation
python train.py hparams/pool_sisnrestimator.yaml --data_folder /yourLibri2Mixpath --base_folder_dm /yourLibriSpeechpath --rir_path /yourpathforwhamrRIRs --dynamic_mixing True --use_whamr_train True --whamr_data_folder /yourpath/whamr --base_folder_dm_whamr /yourpath/wsj0-processed/si_tr_s
```

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