Perceptual Objective Listening Quality Assessment (POLQA), The Third Generation ITU-T Standard for End-to-End Speech Quality Measurement Part II—Perceptual Model

In this and the companion paper Part I, the authors present the Perceptual Objective Listening Quality Assessment (POLQA), the third-generation speech quality measurement algorithm, standardized by the International Telecommunication Union in 2011 as Recommendation P.863. This paper describes the newly developed perceptual model of this standard, allowing to assess speech quality over a wide range of distortions, from “High Definition” super-wideband speech (HD Voice, audio bandwidth up to 14 kHz) to extremely distorted narrowband telephony speech (audio bandwidth down to 2 kHz), using sample rates between 48 and 8 kHz. POLQA is suited for distortions that are outside the scope of PESQ, such as linear frequency response distortions, super-wideband degradations, time stretching/compression as found in Voice-over-IP, certain types of codec distortions, reverberations, and the impact of playback volume. Part II outlines the core elements of the underlying perceptual model and presents the final results.
