Transcoded Speech Contemporary Objective Quality Measurements Reliability
Original language description
Speech transcoding (coder tandeming) is unavoidable source of transmission quality degradation for ad-hoc or permanently interoperating networks. Test methodology and results of voice transmission quality measurement for transcoded voice in coder tandemarrangement is described. The objective tests have been performed using ITU-T P.862 (PESQ) and P.563 (3SQM) algorithms. The subjective tests results based on ITU-T P.800 are also presented. The objective results confirm additional degradations caused byabovementioned transcodings, highlighting coder combinations causing extreme impairments. The subjective tests quantify objective measurement accuracy.
