  ## ESPnet2 ASR model 
  
  ### `pyf98/librispeech_conformer`
  
  This model was trained by Yifan Peng using librispeech recipe in [espnet](https://github.com/espnet/espnet/).
  
  ### Demo: How to use in ESPnet2
  
  ```bash
  cd espnet
  git checkout c3569453a408fd4ff4173d9c1d2062c88d1fc060
  pip install -e .
  cd egs2/librispeech/asr1
  ./run.sh --skip_data_prep false --skip_train true --download_model pyf98/librispeech_conformer
  ```
