Speech denoising using nonnegative matrix factorization with priors
Kevin Wilson, Bhiksha Raj, Paris Smaragdis, Ajay Divakaran · IEEE International Conference on Acoustics Speech and Signal Processing · 2008
We present a technique for denoising speech using nonnegative matrix factorization (NMF) in combination with statistical speech and noise models. We compare our new technique to standard NMF and to a state-of-the-art Wiener filter implementation and show improvements in speech quality across a range of interfering noise types.
