摘要
Abstract
The principle and method of the adaptive filtering and the wavelet transform are analyzed and researched. A new method on speech de-nosing with the adaptive filtering and wavelet transform is proposed. The wavelet decomposition of the speech signal with noise is conducted with the method of the bionic wavelet transform. The noise signal separated by the wavelet transform method is taken as the input signal of the adaptive filter. The adaptive filtering algorithm with least-mean-square (LMS) is adopted to implement de-noising processing, realize signal-noise decomposition and eliminate the noise signal in the speech signal. The experimental results show that the method has a prominent effect on the speech signal de-noising.关键词
