| 摘 要： | 为了更好地滤除语音信号中的宽带噪声,使语音增强向着非线性方向发展。综合考虑语音和噪声特性,选用合理的结构元素,设计了一种新的形态学滤波算法,构造出用于语音信号滤波增强的非线性形态滤波器。仿真实验和数据分析结果论证了这种基于形态学的非线性语音增强方法的可行性,尤其是对于正负脉冲噪声的滤除效果相对较好。

| Abstract: | Non-linear method is the trend of speech enhancement,especially for the speech signal corrupted by wideband noise.In this paper,considering the properties both of the speech and noise signal,a non-llnear morphological filter is designed for suppressing the noises embedded in speech signal.This new tilter,known from the conventional ones, is based on a new morphological filtering algorithm with appropriate structuring element.Simulations results confirm the feasibility and superiority over removing the pulse noise of this new approach. |

| Keywords: | speech enhancement non-linear morphological filtering structuring element |
