Abstract

A new model for the perceptual evaluation of speech quality (PESQ) was recently standardized by the International Telecommunications Union as Recommendation P.862. Unlike previous codec assessment models, such as PSQM and MNB (ITU-T P.861), PESQ is able to predict subjective quality with good correlation in a very wide range of conditions, which may include coding distortions, errors, noise, filtering, delay, and variable delay. The psychoacoustic model used in PESQ is introduced. Part I describes the time-delay identification technique that is used in combination with the PESQ psychoacoustic model to predict the end-to-end perceived speech quality.
