摘要
本文研究了由语音活动检测(VAD)或回波消除器的非线性处理器(NLP)引起的时间裁剪对语音质量的影响。平均意见分数(MOS)作为语音质量的指标。提出了一种基于剪切位置的非侵入式语音质量预测算法。该算法表现出优异的性能，预测结果与实测结果的相关系数约为0.975，预测结果的均方根误差为0.18 MOS
Measurement of the Effects of Temporal clipping on Speech Quality
This paper investigates the effects of temporal clipping, which can result from voice activity detection (VAD), or echo canceller's nonlinear processor (NLP), on speech quality. Mean opinion score (MOS) is used as an index of speech quality. A nonintrusive algorithm, based on the clipping locations, is proposed to predict the speech quality. The algorithm shows excellent performance, the correlation coefficient between the prediction and the measurement is about 0.975, and the root mean square error for the prediction is 0.18 MOS
