Abstract

Communication quality in IP telephony is rated in terms of the Mean Opinion Score (MOS), which is an Absolute Category Rating (ACR) scale. There is a problem when comparing subjectively evaluated MOSs in that the evaluation results are strongly affected by differences in language, the instruction words used for the evaluation, and the nationality of the evaluator. To solve these problems, ITU-T SG12 has started to investigate the cultural and language dependencies of subjective quality evaluations undertaken with the MOS method for speech/video/multimedia. In this paper, we present the results of a comparison of the MOS evaluation characteristics for Chinese, Japanese, and English.
