Practical Issues in Objective Speech Quality Assessment with ITU-T P.862
The ITU-T P.862 Recommendation specifies the Perceptual Evaluation of Speech Quality (PESQ) algorithm that is the current industrial standard for the objective, intrusive assessment of the one-way speech quality of narrowband networks and speech codecs. The practical use of P.862, however, has raised several questions about the robustness, applicability, and accuracy of the algorithm. The current paper presents results from an investigation of these issues. The characteristics of test signals and the interferences of signal interfaces are shown to have a significant effect on the quality assessment with P. 862. A measurement procedure is proposed to define the accuracy of P.862 in the comparison of different or unknown technologies. It is concluded that various test factors should be carefully defined so as different P. 862 measurements to be comparable.
