Abstract

This paper presents an enhanced objective method for VoIP quality evaluation. However, instead of improving the original E-model for G.729, the Simplified E-model has been enhanced using subjective MOS estimation model based-on Thai users, who used Thai-tonal language. The different results from Simplified E-model and subjective MOS estimation model have been used to create the equation called Bias equation, before adding to the Simplified E-model. Based-on the assumption that subjective voice quality evaluation for VoIP is the most authentic and reliable, the results from the enhanced simplified E-model for G.729 show better accuracy when compared to the original simplified E-model obviously.
