加权对数谱距离评价语音通信干扰效果

Jamming Effectiveness Evaluation for Speech Communication Based on Power Added Logarithm Spectrum Distance

介绍了利用两个语音信号序列的加权对数谱距离对语音信号的干扰效果进行评估的方法。给出了归一化距离与干扰效果的主观评价(MOS)之间的对应关系。实验表明该方法对语音干扰效果的评估具有很好的效果。

In this paper, one method of jamming effectiveness evaluation for speech communication based on the power added logarithm spectrum distance of two speech signal is presented. The correspondence relation of power added logarithm spectrum distance to MOS is given. The experimental results and theoretical analysis show that the method has outstanding effect in jamming effectiveness evaluation for speech communication.
