Abstract :
This paper investigates the effects of different language on speech quality in voice over Internet protocol (VoIP) scenarios. We carry out comprehensive experiment to investigate how different languages(English, Chinese) effects on perceived voice quality on different VOIP system factors, which include different kind of delay distribution, codec and packet loss level. Since present-day VOIP speech quality prediction or evaluation models always based on English language, the coefficient or the formula of these model are not really fit VOIP environment in our country. A new parameter relate to language is added to E-Model (ITU G.107). The enhanced E-Model achieves an improved measurement accuracy under different talker condition.
