Perceptual Evaluation of Speech Quality
From Wikipedia, the free encyclopedia
Perceptual Evaluation of Speech Quality (PESQ) is a family of standards comprising a test methodology for automated assessment of the speech quality as experienced by a user of a telephony system. It was standardized as Recommendation ITU-T P.862[1] in 2001. PESQ is used for objective voice quality testing by phone manufacturers, network equipment vendors and telecom operators. Its usage requires a license. The first edition of PESQ's successor POLQA (Recommendation ITU-T P.863[2]) entered into force in 2011.
