+## 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
