## ESPnet2 ENH model 

### `lichenda/Chenda_Li_wsj0_2mix_enh_dprnn_tasnet`

This model was trained by LiChenda using wsj0_2mix recipe in [espnet](https://github.com/espnet/espnet/).

Imported from [zenodo](https://zenodo.org/record/4688000).

### Demo: How to use in ESPnet2

```bash
cd espnet
git checkout 54919e2529d6f58f4550d4a72960f57b83f66dc9
pip install -e .
cd egs2/wsj0_2mix/enh1
./run.sh --skip_data_prep false --skip_train true --download_model lichenda/Chenda_Li_wsj0_2mix_enh_dprnn_tasnet
```
