It is well known that non-intrusive speech quality assessment methods are appropriate for real time monitoring of VoIP traffic. However, previous researches has proved that most of the non-intrusive speech quality assessment methods failed to estimate accurate speech quality using different languages. Consequently, intrusive methods are frequently chosen to provide a more accurate measurement, however they cannot be used for real time VoIP traffic monitoring. In this paper, the technique to enhanced simplified version of ITU-T recommendation G.107 E-model with a language impairment parameter was proposed. The method to estimate the function of language impairment by tuning the E-model with an intrusive objective method, PESQ was presented. The results from statistical analysis show that the modified E-model matches well with PESQ scores in eight languages.
