Japanese ASR
This repository contains all the models and datasets for train/evaluate the Japanese ASR dataset generated through the process of achieving kotoba-whisper models.
Following table shows CER comparison with different data size of ReazonSpeech used to distill openai/whisper-large-v3. The model names follows
japanese-asr/distil-whisper-large-v3-ja-reazonspeech-{size of reazonspeech}.
