Compensating the speech features in the temporal domain via discrete cosine transform for robust speech recognition
碩士 === 國立暨南國際大學 === 電機工程學系 === 99 === In this thesis, we develop a series of algorithms to improve the noise robustness of speech features based on discrete cosine transform (DCT). The DCT-based modulation spectra of clean speech feature streams in the training set are employed to generate two seq...
