Evaluation of objective speech transmission quality measurements in packet-based networks
We analyze the relation between IP channel characteristics and voice transmission quality. To obtain MOS estimation, the ITU-T P.862 PESQ, future P.863 POLQA and P.563 3SQM algorithms are used. Jitter and packet loss decrease quality of transferred voice. POLQA predicts a higher MOS value for most samples.
