## ESPnet2 S2ST model

Vocoder is located [here](https://huggingface.co/espnet/cvss-c_en_wavegan_hubert_vocoder), trained by [realzza](https://github.com/realzza)

### `espnet/jiyang_tang_cvss-c_es-en_discrete_unit`

This model was trained by Jiyang Tang using cvss 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 c002f05ab3ef82938b6a980806cd7f97baba2299
pip install -e .
cd egs2/cvss/s2st1
./run.sh --skip_data_prep false --skip_train true --download_model espnet/jiyang_tang_cvss-c_es-en_discrete_unit
```
