PESQ (based on ITU-T P.862) measures the quality of voice services in terms that directly reflect how a customer perceives their experience. The system employs a reference test signal to make accurate measurements of customer opinion (Mean Opinion Score - MOS) and provides detailed diagnostics information about any degradation present.
PESQ provides highly accurate measurements of perceived performance in terms of MOS, without the need for lengthy or expensive subjective tests.
PESQ provides an overall objective quality score that correlates well with subjective quality ratings obtained from over two hundred thousand subjective test votes.
PESQ produces highly repeatable results especially when used in conjunction with an appropriate test signal such as the Psytechnics Artificial Speech Test Stimulus (ASTS) - a compact test signal designed to maximally exercise voice systems in the minimum amount of time.
