## ESPnet2 Codec model |
|
|
|
### `espnet/libritts_encodec_24k` |
|
|
|
This model was trained by Jinchuan using libritts 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 1974048563d7c57e11f670d24bac8fb4b5aba4ef |
|
pip install -e . |
|
cd egs2/libritts/codec1 |
|
./run.sh --skip_data_prep false --skip_train true --download_model espnet/libritts_encodec_24k |
|
``` |
