  ## ESPnet2 ASR model 
  
  ### `espnet/pt_commonvoice_blstm`
  
  This model was trained by dzeinali using commonvoice recipe in [espnet](https://github.com/espnet/espnet/).
  
  ### Demo: How to use in ESPnet2
  
  ```bash
  cd espnet
  git checkout 716eb8f92e19708acfd08ba3bd39d40890d3a84b
  pip install -e .
  cd egs2/commonvoice/asr1
  ./run.sh --skip_data_prep false --skip_train true --download_model espnet/pt_commonvoice_blstm
  ```
