Voice transmission quality measurement algorithm with non-native listener emulation capability

Abstract

This paper describes the design and verification of algorithm for voice transmission quality measurements in the environment of non-native listeners; it means the communication language differs from the mother tongue of the expected communication service user. The algorithm is based on existing ITU-T P.862 (PESQ) enhanced by newly developed non-nativity emulation block. The calculations in this block are based on subjective test results carried out in compliance with ITU-T P.800 on databases of English and French speech samples affected by various coding distortions and background noise conditions. The results confirm applicability of the developed algorithm in case of non-native communication cases.
