A measure for objective speech quality evaluation of Chinese communication channels

This paper studies briefly a distance measure for objective quality evaluation of Chi-nese communication channels using dynamic spectral features.It is based on studies for subjec-tive and objective quality evaluation and LPC cepstral distance measure.The dynamic spectral features are expressed by the cepstral regression coefficients.We used the three parameters cep-stral coefficients,regression coefficients and log energy to measure objective speech quality.The correlations between 4 sorts of objective distance measure and the subjective quality evaluation (MOS) have been compared;the experimental results show that this objective measure is the best among the 4 sorts of objective distance measure,and the correlation coefficient is 0.954.
