## ESPnet2 ENH model 

### `Johnson-Lsx/Shaoxiong_Lin_dns_ins20_enh_enh_train_enh_dccrn_raw`

This model was trained by Shaoxiong Lin using dns_ins20 recipe in [espnet](https://github.com/espnet/espnet/).

### Demo: How to use in ESPnet2

```bash
cd espnet
git checkout 4538462eb7dc6a6b858adcbd3a526fb8173d6f73
pip install -e .
cd egs2/dns_ins20/enh1
./run.sh --skip_data_prep false --skip_train true --download_model Johnson-Lsx/Shaoxiong_Lin_dns_ins20_enh_enh_train_enh_dccrn_raw
```
