This paper deals with problems of speech transmission quality measurement in TCP/IP networks. It focuses on problems caused by the inaccuracy of current methods for measuring the quality degradation caused by packet loss and jitter. The proposed solution is to use longer samples for listening tests. This article compares three evaluation methods for listening tests.
The main goal of this experiment is to evaluate performance of ITU-T P.863 POLQA in case of low-bitrate coders, namely MELPe, and Chinese language. Performance of POLQA is compared to its predecessor ITU-T P.862 PESQ.
