语音通信质量评价方法的研究

The study of the evaluation method of the quality of speech communication

比较了几种语音通信质量评价算法,提出了一种新的方法即RMFSC(相对美尔谱系数法)。该方法考虑了人耳对频率非线性的感知特性,可以对信道噪声中人耳听不到的低频成分进行过滤,且突出快变信号。

Comparing the algorithms for evaluating speech communication quality, we offer a new method called RMFSC, which considers the sense ability of human ear to the frequency non-linear, filters the low frequency noise out in the communication path and reveals the fast changing signals.
