An evaluation method for the quality of speech under interference based on the phase space configuration

研究了一种基于输出的受干扰语音品质评价方法。利用相空间重构理论,建立了语音信号的相空间结构,在系统分析不同受扰语音相空间结构变化的基础上,提取了特征参数,并用大量的实测数据对这种测度方法进行了验证,结果表明,这种基于相图的受干扰语音品质评价方法是可行的。

In this paper, we suggest an evaluation method for the quality of speech under interference. The method based on the phase space configuration of the output speech signal which is built by using the theory of the phase-space reconstruct. The characteristic parameters for showing the changing of the phase space configuration of speech signals with different S/N are distilled. At last, the method is proved valid using a great deal of test data.
