Abstract: [Engineering Report] ITU-T Recommendation P.563 defines a single-ended method for objective speech quality assessment. The P.563 objective speech quality measurement method predicts the subjective absolute category rating (ACR) listening quality. The accuracy of the P.563 algorithm was tested against data from subjective listening tests. It was found that P.563 compresses the corresponding MOS (mean opinion score) value range for coded speech. For AMR coded speech with GSM and 3G radio channel errors, the MOS value range was from about 1.2 to 4.0, while the corresponding P.563 MOS-LQO range was from about 3.0 to 3.6. The quality of the modulated noise reference unit (MNRU) and direct samples was predicted better.
