Perceptual Objective Listening Quality Assessment (POLQA) and Perceptual Evaluation of Speech Quality (PESQ) are commonly used objective standards for evaluating speech quality. These methods were developed and trained on native speakers’ speech sequences of some western languages. One can then wonder how these methods perform if they are applied to other languages or if the speaker is non-native. This paper deals with the evaluation of PESQ and POLQA on languages that were not been considered when setting up these methods, with emphasis on Moore and Dioula, two local languages of Burkina Faso. Another aspect is the evaluation of these two methods in the case of non-native speakers. For this purpose, in the one hand, the Mean Opinion Score-Listening Quality Objective (MOS-LQO) of PESQ and POLQA, computed for Moore and Dioula, are compared to those of French and English. On the second hand, the MOS-LQO scores of French and English are compared for native and non-native speakers, to evaluate the effect of the accent of speakers.
