A Study of Noise Suppression Approaches based on Nonnegative Matrix Factorization for Speech Enhancement
碩士 === 國立暨南國際大學 === 電機工程學系 === 102 === In this thesis, we exploit the technique of nonnegative matrix factorization (NMF) in speech enhancement, considering the sub-band and temporal patch characteristics of noisy spectrogram. We investigate the segmental NMF scheme in speech enhancement and compare...
