摘要
实验性地研究了一种将人耳前向掩蔽效应用于巴克谱失真测度的方法。测试语音条件为G729编码受扰语音和调制噪声参考单元MNRU,实验结果表明,这种改进的巴克谱失真测度与普通的巴克谱测度相比具有更好的相关性。
This paper briefly describes a Modified Bark Spectral Distance measure of objective speech quality evaluation with the auditory forward masking effects. Testing speech is jammed G729 and MNRU. Experimental results show that the correlative coefficient of MBSD over the conventional BSD.
