Hi,

Do we need to do any noise cancellation or pre-emphasis on the speech
signal before feeding to the DeepSpeech model for inference. Or is there
such a approach inside the DeepSpeech Inference model.

Thanks in Advance

We are working on improving the training to make the model deal better
in noisy environment, so, as of today, it could only help if you do some
noise cancellation before hand.
