摘要
通过对维纳滤波的介绍,实现了基本维纳滤波效果;利用两级维纳滤波和两级滤波器组滤波方法实现了语音增强,达到了良好的效果。
The principles of Wiener filtering are introduced and the basic effect of wiener filtering is realized. Through further two-stage Wiener filtering and two-stage filter bank filtering, the speech enhancement is realized and the effect is satisfying.
