## ESPnet2 ASR model

### `espnet/sluevoxceleb_owsm_lightweight_asr`

This model was trained by “siddhu001” using slue-voxceleb 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 e23ef85f0b3116ad5c60d0833f186da0deec0734
pip install -e .
cd egs2/slue-voxceleb/slu1_asr
./run.sh --skip_data_prep false --skip_train true --download_model espnet/sluevoxceleb_owsm_lightweight_asr
```
