esc-benchmark/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="esc-benchmark/wav2vec2-ctc-pretrained" \
