POLQA ''Perceptual Objective Listening Quality Assessment'', also known as ITU-T Rec. P.863〔http://www.itu.int/rec/T-REC-P.863/en ITU-T Recommendation P.863: Perceptual objective listening quality assessment〕 is an ITU-T Standard that covers a model to predict speech quality by means of digital speech signal analysis.
----
== Measurement scope ==
POLQA covers a model to predict speech quality by means of digital speech signal analysis. The predictions of those objective measures should come as close as possible to subjective quality scores as obtained in subjective listening tests. Usually, a Mean Opinion Score (MOS) is predicted. POLQA uses real speech as a test stimulus for assessing telephony networks.
