Abstract:

The accuracy of perceptual evaluation of speech quality (PESQ) in assessing speech codec in Chinese environment was investigated, an improved algorithm was proposed. Due to the lack of research about PESQ evaluate speech codecs under Chinese environment, an experiment was done based on Chinese speech database to get accuracy of PESQ for evaluate two codecs under Chinese database. And the reason of the experiment result was analyzed. In order to improve the accuracy of PESQ for speech codec, an improved PESQ algorithm was proposed.

Key words: quality of experience, perceptual evaluation of speech quality, speech codec
