## ESPnet2 DIAR model 

### `soumi-maiti/libri2mix_eend_ss`

This model was trained by soumimaiti using librimix 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
git checkout d837c97c88f13ffe655a30bcff93d814f212b225
pip install -e .
cd egs2/librimix/enh_diar1
./run.sh --skip_data_prep false --skip_train true --download_model soumi-maiti/libri2mix_eend_ss
```
