A Study on Single Channel Speech Enhancement Using Critical-Band-Wavelet-Packet Transform

A Study on Single Channel Speech Enhancement Using Critical-Band-Wavelet-Packet Transform

博士 === 國立清華大學 === 電機工程學系 === 94 === In this dissertation, we present two new techniques for single channel speech enhancement. These techniques reduce the noise in each subband based on the critical-band-wavelet-packet decomposition. A noise masking threshold (NMT) is employed to adjust wavelet-coef...
