The ITU-T P.862 standard, also known as Perceptual Evaluation of Speech Quality (PESQ), is a widely used objective method for assessing the quality of speech codecs and telecommunication networks by predicting human perception of speech quality. It provides a standardized way to measure and compare the performance of different speech processing systems, ensuring consistency and reliability in telecommunication services.

Perceptual Evaluation of Speech Quality (PESQ) is a standardized method used to objectively measure the quality of speech as perceived by human listeners, often applied in telecommunications to assess the performance of voice codecs and networks. It compares the original and degraded audio signals to produce a quality score that correlates highly with subjective listening tests.
