Advice in Noise Suppression in Voice Processing Context

Started by andrewstanfordjason 7 years ago1 replylatest reply 7 years ago154 views

Hello, I am playing with noise suppression for voice processing applications. I have done a bit of reading and thought it sensible to ask if anyone could advise me as to a good place to start. I am familiar with spectral subtraction and have played with it a bit but avoiding artefacts seems to be an issue. Any advice would be appreciated with techniques or post processing to remove artefacts. Thanks

NB: I am assuming a office/home environment (not an F16).
