Abstract
This paper presents comparison of VoIP quality from four VoIP applications, Kakao, Line, Skype and Viber. This study was conducted with Thai and English speech files over a broadband network in one province near Bangkok based on the best efforts before gathering the degraded speech files. Then, those files have been processed using Perceptual Evaluation Speech Quality Technique (PESQ) in order to obtain the VoIP quality values called MOS, which stands for mean opinion score. It has been found that there is no significant difference between three of the VoIP applications with a slight difference for Kakao over LINE over Skype. While Viber provides the lowest VoIP quality when compared to the other VoIP application obviously. The major contribution of this work is the first evidence that surprisingly reports VoIP quality with slight difference from Kakao over Skype and LINE, two major players in this arena. ฉ 2015 IEEE.
