摘　　要：本文采用以谱距离为基础的LPC CD、Bark SD和Mel CD三种客观失真测度 ,对若干种语音编码设备及它们的级联系统进行了客观音质评价实验研究 .结果表明 ,这三种测度单独应用都具有较好主、客观相关性 ,它们的组合 ,给出更好的相关结果 .因此 ,可以推断 ,这些测度作为语音系统的音质评价是有一定有效性和实用性的 .Using the LPC CD,Bark SD and Mel CD distortion measures,we experimentally study the Objective Quality Eva luation of a large number of the speech systems.The result shows that each of these measures gives better correlation between objective and subjective measurement when they are used independently to those systems.Combining their results through a weighted and average way,higher correlation coefficient can be given,we can conclude that these measures have certain validity and utility to appraise the quality of speech systems.
