用于语音干扰效果评估的加权对数谱分析法

Application of Logarithm Chart Analysis in Speech Communication Quality

语音通信质量客观评估方法是当前声学技术研究领域的一个重要课题。在介绍语音音质评估一般方法的基础上,对基于巴克谱的客观评估结果进行分析对比后发现,评估结果中失真距离与主观评估的一致性较差,提出了基于加权对数谱分析的语音干扰效果客观评估方法,使评估结果更加可靠。

The impersonally evaluation of the speech communication quality is an important problem in acoustic technology research domain. By general method based on barker code of speech quality evaluation,the objective speech jamming effect evaluation menthod founded on weighted logarithm spectrum analysis is given. The consistency between the distortion distance of evaluation result and subjective evaluation is analyzed and compared.
