Perceptual Objective Listening Quality Analysis
open-in-new
<p>P.OLQA was the working title of an <a href="/facts/ITU-T/9nJwkPYx">ITU-T</a> standard that covers a model to predict speech quality by means of analyzing digital speech signals. The model was standardized as Recommendation ITU-T P.863 (Perceptual objective listening quality assessment) in 2011. The second edition of the standard appeared in 2014, and the third, currently in-force edition was adopted in 2018 under the title Perceptual objective listening quality prediction. P.863 is known in the field under the name POLQA, which is often misinterpreted as "Perceptual Objective Listening Quality Analysis", but in fact, POLQA is no abbreviation and the "P" in the name stems from the P Series of ITU-T Recommendations. </p>
