# Open Large Bengali ASR Data

This is a collection of publicly available ASR data for Bengali. It contains **5000 hours** of audio. We have a filtering column called *is_better* to filter good-quality audio from the corpus. It is set based on the *wer* between original transcription and prediction taken from a Bengali-Wav2Vec2 model and *word-per-second (wps)*.
