Performance Study of PESQ for AMR-WB Speech Codec
Abstract:In this paper we study the PESQ (perceptual evaluation of speech quality) algorithm. An experiment was done to get performance of PESQ in AMR-WB(Adaptive Multi-Rate Wideband), and the result was analyzed. We proposed an improved PESQ called APESQ, and the APESQ improved the accuracy of evaluation of AMR-WB speech codec.
Keywords: quality of experience Perceptual evaluation of speech quality speech codec
