An object evaluation is introduced and compared with traditional Mean Opinion Score(MOS) ( MOS ). 引入了一种客观语音质量评价方法,并与传统的主观评价平均意见分相比较。
The formal Mean Opinion Score(MOS) ( MOS ) obtained subjectively is compared with the result. 最后再将计算结果与主观评测(MOS)的结果进行比较。
Experiments show that the correlation coefficient between the proposed approach and the human subjective assessment mean opinion score ( MOS ) is 0.92, much higher than 0.69, the correlation coefficient of conventional PSNR with MOS. 实验结果表明,该方法和人的主观评价方法MOS的相关系数为0.92,大大高于常用的峰值信噪比和MOS的相关系数0.69。
This paper utilizes MOS ( Mean Opinion Score(MOS) ) as the subjective evaluation. The three objective evaluation indicators are SNR ( Signal-to-Noise Ratio ), CC ( Correlation Coefficient ), and Kurtosis. 本文中,主观评价方法采用的是平均意见得分(MOS)法,客观评价方法采用了信噪比、相关系数和峭度三个指标。
This paper presents the formula of the speech quality evaluation incorporating the Bark spectrum distortion and the ratio of the muted and noise frames. Calculational results are comparied with the mean opinion score ( MOS ). 文中同时给出了结合巴克谱失真和弱音与噪声帧比率的语音质量评估公式,并将计算结果与平均意见分(MOS)进行了比较。
