GL Announces Release of Enhanced Voice Quality Testing Solutions

February 22, 2013

GL Communications Inc.,  a provider of PC-based test, analysis and simulation products and consulting services, has introduced its latest enhanced Voice Quality Testing Software with Perceptual Objective Listening Quality Analysis (POLQA) standard.

"GL's enhanced VQuad 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 (ITU-T P.863),” said Robert Bichefsky senior manager for product development of the company.” .

Bichefsky added that the VQT supports other international standard voice quality test methods including PESQ (ITU-T P.862), PESQ LQ / LQO (P.862.1), PESQ WB (P.862.2), PAMS (ITU-T P.800), and PSQM/PSQM+ (ITU-T P.861).  In addition, it:

  • Supports the latest HD-quality speech coding and network transport technology with higher accuracy for 3G, 4G/LTE (News - Alert) and VoIP networks, and is based on ITU standard, ITU-T P.863 which is the successor of PESQ (ITU-T P.862) analysis. 
  • Adds for the first time Voice Quality (POLQA) directly to the VQuadTM as an option.

Bichefsky pointed out that the POLQA algorithm avoids weaknesses of the current PESQ model and handles the higher bandwidth audio signals including wideband (WB, 300-3400 Hz) and super-wideband (SWB, 50-14000 Hz). Further improvements of this algorithm include the handling of signals with many delay variations and support for assessment of speech signals recorded acoustically by HATS (head and torso simulator).

POLQA, similar to PESQ, is a Full Reference (FR) algorithm that rates a degraded or processed speech signal in relation to the original (reference) signal. POLQA analyzes the degraded speech signal sample-by-sample after a temporal alignment of the reference test signal. Perceptual differences between both signals are scored as differences. The perceptual psycho-acoustic model is based on similar models of human perception.

TMCnet recently reported that GL Communications (News - Alert) has unveiled its software for Echo Performance Testing and Verification which allows IT professionals to apply delay, attenuation, and/or filtering to a received signal on any number of timeslots.
