GL Communications says its Voice Quality Analysers are now enhanced to support Perceptual Objective Listening Quality Analysis (POLQA) version 3.0.
“POLQA, the successor of Perceptual Evaluation of Speech Quality (PESQ) (ITU-T P.862) analysis, is the next generation voice quality testing standard for fixed, mobile and IP-based networks,” says Robert Bichefsky, director of engineering at GL Communications.
”Based on ITU-T P.863 standard, POLQA supports the HD-quality speech coding and network transport technology, with higher accuracy for 3G, 4G/LTE and VoIP networks. Upgrading to the 3rd edition of ITU-T P.863, POLQA extends its scope and applicability towards 5G telephony and OTT codecs”
He further adds: “The latest version of GL’s Voice Quality Analysers support the optional POLQA v3 upgrade from POLQA v2.4. POLQA v3 supports full band audio analysis which provides improved scoring for mobile-based VoLTE, 5G and OTT applications using EVS and OPUS codecs. POLQA v3 is more sensitive to distortions across the entire audio spectrum. In addition, POLQA v3 supports less harsh analysis of micropauses within the speech, reacts with less sensitivity to linear frequency distortions and includes a significantly improved and streamlined perceptual model”.
