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

#!/usr/bin/env bash

Set bash to 'debug' mode, it will exit on :

-e 'error', -u 'undefined variable', -o ... 'error in pipeline', -x 'print commands',

set -e set -u set -o pipefail

train_set=train valid_set=dev test_sets="dev test1"

asr_config=conf/train_asr_whisper_large_lora_finetune.yaml inference_config=conf/decode_asr_whisper_noctc_beam10.yaml

lm_config=conf/train_lm_transformer.yaml use_lm=false use_wordlm=false

speed perturbation related

(train_set will be "${train_set}_sp" if speed_perturb_factors is specified)

speed_perturb_factors="0.9 1.0 1.1"
