PVQA 1.9 vs ViSQOL on two public MOS corpora (NISQA, TCD-VoIP). PVQA leads on Pearson r, Spearman rho and share of clips within 0.5 MOS across all three sets — biggest gap on TCD-VoIP (r 0.82 to 0.91).
VQ Monitor for Asterisk: a free module (res_vq_monitor.so) reporting Network MOS, packet loss, jitter, R-factor and SIP timing on every call, with a small web dashboard. Open-source module and frontend, free-EULA engine.
Being a multipurpose tool for voice quality analysis PVQA Server can be the core of a quality analysis and monitoring system to detect and investigate QoE and QoS related issues. PVQA Server combines the force of audio waveform analysis using PVQA technology with continuous network monitoring:
🔎Real-time call quality monitoring
🔎Proactive maintenance based on non-intrusive waveform analysis
🔎Monitoring network and media quality simultaneously
🔎Matching network metrics (RTT, jitter, latency, packet loss) with payload metrics (noise, clipping, dead air, echo etc)
We would like to announce pre-release of new versions of AQuA and PVQA that introduce Machine Learning engine integrated into both technologies. With these new tools our customers now can train perceptual models of AQuA and PVQA to provide MOS (Mean Opinion Score) scores that better conform real user quality of experience. Please contact us for demonstration and evaluation.
