## ESPnet2 EnhS2T model 

### `Yoshiki/chime4_enh_asr1_wpd_wavlm_conformer`

This model was trained by Yoshiki using chime4 recipe in [espnet](https://github.com/espnet/espnet/).

### Demo: How to use in ESPnet2

Follow the [ESPnet installation instructions](https://espnet.github.io/espnet/installation.html)
if you haven't done that already.

```bash
cd espnet
8ed83f45d5aa2ca6b3635e44b9c29afb9b5fb600
pip install -e .
cd egs2/chime4/enh_asr1
./run.sh --skip_data_prep false --skip_train true --download_model Yoshiki/chime4_enh_asr1_wpd_wavlm_conformer
```
