chinese-hubert-base

Pretrained on 10k hours WenetSpeech L subset. More details in TencentGameMate/chinese_speech_pretrain

This model does not have a tokenizer as it was pretrained on audio alone. In order to use this model speech recognition, a tokenizer should be created and the model should be fine-tuned on labeled text data.
