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.

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"
