Abstract(in English) | In general, speech is nonlinearly degraded by noise, affecting the speech spectrum and cepstrum in various ways. In this paper, we discuss noise reduction using a neural network and a regressive analysis. The method using the neural network learns the normalized cepstrum directly. For modeling the effect of noise, the method of regressive analysis quantizes the learning data into a vector before regressive analysis in order to deal with nonlinear change. We use spectral distortion to evaluate this experiment. At most, each mtehod reduces spectral distortion by 2dB. |
