| 摘 要： | 系统研究了现有语音通信系统中使用的几种语音编解码算法以及主流的单通道语音增强算法,并将二者相结合,对实际通信系统中的结构进行仿真.研究发现,现有的基于线性预测分析技术的语音编解码算法,在高编码率的情况下对于语音增强算法的性能不仅不会有损失,反而会在一定程度上改善增强算法带来的语音失真的情况,提高语音增强算法的效果.

| Abstract: | Some speech codec methods and single-channel speech enhancement algorithms are studied.And these two functions are combined to simulate the real telecommunication system.It is concluded that basically in high coding rate,the linear prediction(LP) analysis based speech codec methods do not affect the speech enhancement algorithms,and sometimes reduce the speech distortion owing to the excessive enhancing.So the results of the speech enhancement can be increased. |
