以最小均方误差(LMS)为基础,对自适应滤波器的降噪方法进行介绍与阐述,并通过实验来验证自适应滤波器的降噪作用,希望能够从理论层面上为自适应滤波器在语音识别中的应用与发展提供一点支持。
Based on the minimum mean square error (LMS), this paper introduces and expounds the noise reduction method of adaptive filter, and verifies the noise reduction effect of the adaptive filter through experiments. It is hoped that the adaptive filter In speech recognition applications and development to provide some support.
