Closed luomingshuang closed 2 years ago

luomingshuang commented 2 years ago

We have a new version snowfall. But the aishell recipe codes don't update. The aishell recipe codes can't run based on the current version snowfall. I notice some people still use this repository for Chinese ASR. So I take some time to update the aishell recipe codes to adapt the current version snowfall. Also, I have run experiments based on the new aishell recipe and got some good results. The results are as follows:

About the directory "local2", I copy the files from librispeech/asr/simple_v1/local2 and just adjust the add_silence_to_transcript.py.
