几种单通道的语音增强算法研究

The Search of Single Channel Speech Enhancement Algorithms

对目前常用的几种单通道语音增强算法,即谱减法、最小均方误差估计以及子空间算法进行研究,通过仿真实验对三种单通道语音增强算法的去噪效果和去噪后语音失真程度以及信噪比进行比较分析,由此论证三种方法的使用条件和在该条件下的增强效果。

The paper compares the commonly used several kinds of single channel speech enhancement algorithms, such as spectral subtraction, minimum mean square error estimation and subspace algorithm. Through the experiments, the paper aims at arguing the performance of the three kinds of single channel speech enhancement algorithms and gains the condition and environment of using the algorithms..
