- K. Wilson, B. Raj, P. Smaragdis, Ajay Divakaran. 2008. Speech denoising using nonnegative matrix factorization with priors. Abstract: 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.
