(MENAFN- GlobeNewsWire – Nasdaq)
GAITHERSBURG, Md., April 05, 2022 (GLOBE NEWSWIRE) — GL Communications Inc., a worldwide chief in telecom check and measurement options, addressed the press relating to their Voice High quality Testing (VQT) Options for fastened, cellular, and IP-based networks utilizing Perceptual Goal Listening High quality Evaluation (POLQA) and Perceptual Analysis of Speech High quality (PESQ) requirements.
“GL’s VQT software program makes use of broadly accepted algorithms to supply measurements of voice high quality over all forms of networks together with ATM, VoIP, PSTN, and Mobile. It helps next-generation VQT algorithms for IP networks utilizing POLQA per ITU-T P.863, and PESQ per Rec. P.862.1 and P.862.2,” stated Robert Bichefsky, Director of Engineering at GL Communications Inc.
He additional added,“The PESQ algorithm offers an goal measurement of subjective listening exams on telephony techniques. The POLQA algorithm is a next-generation voice high quality testing normal for fastened, cellular, and IP-based networks and helps the newest HD-quality speech coding and community transport expertise, with greater accuracy for 3G, 4G/LTE, 5G, and VoIP networks together with Over-The-High (OTT) apps and Voice over Wi-Fi (VoWiFi). The algorithm additionally offers Sign and Noise Ranges together with Jitter measurements.”
Transferring ahead with the optionally available POLQA v3 launch helps Full Band Audio Evaluation which offers improved scoring for mobile-based Voice over Lengthy-Time period Evolution (VoLTE), 5G, and OTT functions utilizing EVS and OPUS codecs. It additionally helps a much less harsh evaluation of micro pauses throughout the speech, reacts with much less sensitivity to linear frequency distortions, and features a considerably improved and streamlined perceptual mannequin.
The GL VQT software program is a standalone product that may be configured for totally automated operation. As soon as the VQT utility detects a PCM/WAV voice (degraded voice) file in a user-specified listing, the VQT software program will routinely apply the algorithm towards the reference and degraded PCM/WAV voice information and compute a Imply Opinion Rating (MOS).
GL VQT software program helps distant operation utilizing the Command Line Interface (CLI) and Utility Programming Interface (API) features supporting WinOS, Linux, and macOS. The outcomes of the VQT algorithm are reported instantly within the stand-alone VQT utility whereas additionally being saved to VQT log information. These outcomes can be despatched to a Central Database the place GL’s web-based dashboard, referred to as WebViewer
Key Options
- Take a look at voice high quality over all forms of telecom networks—Wi-fi, VoIP, TDM, and PSTN
