Extensive Bark Spectral Distortion Measurement for Objective Speech Quality Assessment

The performance of the Extensive Bark Spectral Distortion EBSD measure is examined for speech data with coding distortions by varying the scaling the noise masking threshold and omitting the spreading function in noise masking threshold calculation. Some comparative experiment results of the EBSD and Bark Spectral Distortion(BSD) show that the EBSD has better performance than BSD in Chinese communication channels, and the correlation coefficient reaches 0.969.
