Abstract

Abstract

This paper analyses various objective measures for the prediction of subjective quality of speech. A new Perception-based Bark Spectral Distortion (PBSD) parameter is pre- sented, which takes the masking property of human ear into consideration, to predict Mean Opinion Score(MOS) of speech quality. Experiments prove that this map from objective mea-sure to subjective MOS based on the calculation of PBSD has rather small prediction error. The PBSD parameter is applied to designing new speech codec in place of MSE parameter and the subjective quality of decoded speeches is improved.
