## ESPnet2 AVSR model

### `espnet/msk_lrs3_train_avsr_avhubert_large_extracted_en_bpe1000`

This model was trained by ms-dot-k using lrs3 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
pip install -e .
cd egs2/lrs3/avsr1
./run.sh --skip_data_prep false --skip_train true --download_model espnet/msk_lrs3_train_avsr_avhubert_large_extracted_en_bpe1000
```
