Abstract

In objective assessment methods of speech quality, Mel cepstrum coefficients are usually used as speech feature parameters. However, the effect of the Mel cepstrum order and the component contribution were not involve in the previous research. After determining the optimal order, the contribution of the Mel cepstrum coefficient is studied in combination with the increasing or decreasing component method. The lower Important Mel Frequency Cepstrum coefficient (IMFCC) was obtained after the selection and recombination of the feature parameters. After testing, the assessment effect is improved and the prediction error is reduced.
