A Preliminary Study of Nonnegative Matrix Factorization for Enhancing the Modulation Spectrum of Speech Signals
碩士 === 國立暨南國際大學 === 電機工程學系 === 104 === In this thesis, we propose to enhance the modulation spectrum of the spectrograms for speech signals via the technique of non-negative matrix factorization (NMF). In the training phase, the clean speech and noise in the traing set are separately transformed to...
