Perceptual Quality Assessment of Telecommunications Systems Including Terminals.

Perceptual quality measurement algorithms such as PESQ (ITU-T Recommendation P.862) are now in common use for evaluation of speech quality of communications networks and systems. However these algorithms are mainly designed for use with electrical or digital ' not acoustic ' interfaces to the systems under test. This limits the algorithms' applicability to terminals, in particular where the effects of transducers, acoustics, and signal processing in the terminals may be combined with network properties such as low bit-rate coding and channel errors. This paper describes work under way in ITU-T SG12 to develop a new algorithm for evaluation of both networks and terminals using acoustic interfaces, and reports the latest results in the development of a new ITU-T Recommendation for this application.
