  ## ESPnet2 ASR model
  
  ### `espnet/shihlun_asr_whisper_medium_finetuned_chime4`
  This model was trained by Shih-Lun Wu (slseanwu) using the chime4 recipe in [espnet](https://github.com/espnet/espnet/).
  
  ### Demo: How to use in ESPnet2
  ```bash
  cd espnet
  pip install -e .
  cd egs2/chime4/asr1
  
  train_set=tr05_multi_noisy_si284 # tr05_multi_noisy (original training data) or tr05_multi_noisy_si284 (add si284 data)
  valid_set=dt05_multi_isolated_1ch_track
  test_sets="dt05_real_isolated_1ch_track dt05_simu_isolated_1ch_track et05_real_isolated_1ch_track et05_simu_isolated_1ch_track"
  
  asr_tag=whisper_medium_finetune_lr1e-5_adamw_wd1e-2_3epochs
  asr_config=conf/tuning/train_asr_whisper_full.yaml
  inference_config=conf/decode_asr_whisper_noctc_greedy.yaml
