Effect of speech activity parameter on PESQ's predictions in presence of independent and dependent loses
Original language description
The paper deals with the investigation of PESQ's (Perceptual Evaluation of Speech Quality; also known as ITU-T Recommendation P.862) behavior under independent and dependent loss conditions from a speech activity parameter perspective. The results show that an increase in amount of speech in the reference signal (expressed by the activity parameter) may result in an increase of the PESQ sensitivity to packet loss change as well as PESQ's prediction accuracy improvement. On the other hand, it seems thathuman brain is a bit less sensitive to loss of some parts of words than PESQ. The reasons for those findings are particularly discussed.
