esb/wav2vec2-ctc-chime4

To reproduce this run, first call get_ctc_tokenizer.py to train the CTC tokenizer and then execute the following command to train the CTC system:

#!/usr/bin/env bash
python run_flax_speech_recognition_ctc.py \
        --model_name_or_path="esb/wav2vec2-ctc-pretrained" \
        --tokenizer_name="wav2vec2-ctc-chime4-tokenizer" \

        --dataset_config_name="chime4" \
        --output_dir="./" \
