  ## ESPnet2 ASR model 
  
  ### `espnet/tamil_slu`
  
  This model was trained by Sujay S Kumar using tamil recipe in [espnet](https://github.com/espnet/espnet/).
  
  ### Demo: How to use in ESPnet2
  
  ```bash
  cd espnet
  git checkout 395bda6123ae268f991e5ef1dab887b6e677974a
  pip install -e .
  cd egs2/tamil/asr1
  ./run.sh --skip_data_prep false --skip_train true --download_model espnet/tamil_slu
  ```
