Abstract :
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.
