FEATURES OF THE DIFFERENT METHODS POLQA
PESQ Defined two operating modes: Defines several versions in order to Super Broadband mode with the compare notes of different following bandwidths: technologies: Operating * Super broadband mode * broadband * PESQ-Wide Band (WB) * Narrow broadband Narrowband mode for narrowband * PESQ-Narrow Band (NB) networks.
While emphasizing on the enhanced Voice Analysis Testing Tools, he explained, "GL's Voice Quality Testing (VQT) software supports the POLQA
(ITU-P.863) and PESQ (ITU-P.862) algorithms.
Today, mainly two standards are used for analysing voice quality in mobile networks - PESQ and POLQA
. It is understoond that POLQA
will become more commonly adopted by operators as new codecs and IP based Voice over LTE (VoLTE) are introduced.
Robert Bichefsky Senior Manager for product development of the company said, "GL's enhanced VQuad(TM) and stand-alone Voice Quality Testing (VQT) software, both support the next-generation voice quality testing standard for fixed, mobile and IP-based networks using POLQA
also supports user-specified Sampling Rate (specify any rate between 8K to 48K) and POLQA
ITU version 2.4 for POLQA
NB and SWB (including WB) modes.
PESQ and now POLQA
enable an APx analyzer to take psychoacoustic factors into account and assign an MOS objectively.
"It also provides the features of transferring of recorded voice file automatically to the central system for voice quality analysis using POLQA
He added, "VQuad[TM] with Dual UTA HD supports Audio for Voice Quality (using GL VQT POLQA
algorithm), Path Recognition and Prompt Recognition.
