Disable noise augmentation

Open AlexandderGorodetski opened this issue 2 years ago • 1 comments

Hello guys,

I have a question regarding tedlium3 recipe. I see that during tedlium data preparation, fbank is extracted for tedlium and for musan. Therefore I assume that during the training noise augmentation is performed. Could you please point me in the code how can I disable this noise augmentation.

Thanks a lot, AlexG.

Please pass

--enable-musan 0

to ./train.py to disable musan.
