摘要

我们提出了两种技术，可用于增强感知语音质量的客观估计。描述了帧归一化和帧-能量平面划分，并将其应用于基于对数频谱误差的估计器。将得到的估计量相互比较，并与两个已建立的估计量进行比较。这是通过与17个正式主观测试的MOS值的相关性来完成的。我们发现所提出的技术显著改善了基于对数光谱误差的估计。

Advances in objective estimation of perceived speech quality

We present two techniques that can be used to enhance objective estimators of perceived speech quality. Frame normalization and frame-energy plane partitioning are described and applied to a log-spectral-error-based estimator. The resulting estimators are compared with each other and with two established estimators. This is done through correlation with MOS values from 17 formal subjective tests. We find that the proposed techniques significantly improve the log-spectral-error-based estimator.
