## ESPnet2 DIAR model 

### `espnet/YushiUeda_mini_librispeech_diar_train_diar_raw_valid.acc.best`

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

### Demo: How to use in ESPnet2

```bash
cd espnet
git checkout 650472b45a67612eaac09c7fbd61dc25f8ff2405
pip install -e .
cd egs2/mini_librispeech/diar1
./run.sh --skip_data_prep false --skip_train true --download_model espnet/YushiUeda_mini_librispeech_diar_train_diar_raw_valid.acc.best
```
