摘　　要：文章研究了基于人耳听觉特性的 Ｂａｒｋ 谱测度评价方法。由若干测试语音条件的客观失真距离和偏差的计算结果表明，该测度具有较高的主、客观相关系数，并在此基础上，与 Ｌ Ｐ Ｃ－ Ｃ Ｄ 测度进行了比较。This paper carries out research on the Bark spectral distance measure,which based on perceptually-motivated model.Experimental results of a great deal of the test conditions show that there exist high correlation between the results of subjective test and objective measure computation.On the basis of the previous research,we made a comparison between the Bark spectral distance measure and LPC spectrum distance measure.

关 键 词：客观音质评价 Bark谱测度 语音信号处理
