Abstract

In this paper, an objective measurement for speech quality evaluation based on auditory characteristics is proposed. Firstly, the features are extracted by the Gammatone auditory filter bank to calculate the Gammatone Frequency Cepstrum Coefficient (GFCC) of the original speech and the distortion. After getting the GFCC, the average distortion distance is obtained. Then, in order to get an objective estimator for the objective Mean Opinion Score (MOS), it is necessary to map the normalized average distortion distance to the MOS scale. Experiments show that the proposed algorithm can greatly reduce the algorithm complexity. At the same time, the relevancy between the subjective MOS and the objective MOS is close to the Perceptual Evaluation of Speech Quality (PESQ). It is proved that the new algorithm is useful for the real-time online monitoring of the speech quality.
