Mel-Spectral Distortion Measure Based on Perception Model for Objective Speech Quality Assessment

  • 摘要: 为了有效评价通信系统中的语音质量,基于语音感知分析,提出了M el域上一种新的语音信号特征表示方法———MFSC(美尔谱系数).MFSC既考虑人耳对频率的非线性感知特性,又结合了声音强度-响度非线性变换特性,符合语音感知分析.基于MFSC特征参数的提取,提出了用于语音质量客观评价的美尔谱失真测度(M el-SD),并将其应用于干扰条件下的无线通信系统语音质量评价.实验结果表明,M el-SD的平均相关值为0.942,分别比M el-CD和PESQ(语音质量感知评价)提高了0.089和0.031.
