A performance evaluation method for objective measures estimating subjective quality of coded speech is proposed and applied the comparison of existing objective quality measures. The measure based on Bark spectrum distortion performs the best. Comparing its estimation error with the statistical reliability of subjective quality assessment shows that objective quality measurement can be as reliable as subjective measurements for some testing conditions.
