Perceptual evaluation of speech quality (PESQ)-a new method for speech quality assessment of telephone networks and codecs
TL;DR: A new model has been developed for use across a wider range of network conditions, including analogue connections, codecs, packet loss and variable delay, known as perceptual evaluation of speech quality (PESQ).
Journal Article
PEAQ - The ITU Standard for Objective Measurement of Perceived Audio Quality
Thilo Thiede,William Treurniet,Roland Bitto,Christian Schmidmer,Thomas Sporer,John G. Beerends,Catherine Colomes +6 more
TL;DR: In this article, a new measurement method is described that combines ideas from several earlier methods, and the method should meet the requirements of the user community, and it has been recommended by ITU Radiocommunication study groups.
Journal Article
A Perceptual Audio Quality Measure Based on a Psychoacoustic Sound Representation
TL;DR: In this article, a general method for predicting subjectivity quality of speech codecs is developed using the concept of an internal sound representation, which is used to calculate the internal representation of the input and output signals of a speech codec.
Journal Article
Perceptual Evaluation of Speech Quality (PESQ) The New ITU Standard for End-to-End Speech Quality Assessment Part II: Psychoacoustic Model
TL;DR: In Part I time-delay identification techniques are introduced and some causes of variable delay are outlined before the processes that are integrated into PESQ and specified in P.862 are described.
