## ESPnet2 DIAR model 

### `YushiUeda/callhome_adapt_real`

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

### Demo: How to use in ESPnet2

```bash
cd espnet
git checkout 0cabe65afd362122e77b04e2e967986a91de0fd8
pip install -e .
cd egs2/callhome/diar1
./run.sh --skip_data_prep false --skip_train true --download_model YushiUeda/callhome_adapt_real
```
