ABSTRACT: 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.
