摘要
研究能够减小声音信号中噪声成分的一种处理方式其原理基于模糊模式识别理论和信号的功率谱及其自相关函数互为博里叶变换对的理论．该方式可较好地达到减小噪声和防止子音失落的目的．
In this paper, we propose a new system which can reduce to a certain degree the noise component of voice signal. The principle of this system is based on the fuzzy pattern information processing, and the power spectrum and the auto correlation form a Fourier transform pair each other. It is easy to find thet the final signal contains little noise component.
