The study of sub-band modulation spectrum factorization in robust speech recognition
碩士 === 國立暨南國際大學 === 電機工程學系 === 100 === In this paper, we propose to enhance the modulation spectrum of speech features in noise robustness via the technique of non-negative matrix factorization (NMF). With NMF, a set of non-negative basis spectra vectors is derived from the clean speech to represent...
