PVQA Sevana Test and Measurement

Do you want to know about call quality issues prior your customers start complaining?

Sevana libraries collect all the QoS and QoE data of the calls in real-time, providing immediate alerting on changes that affect callers’ perception, discover and store reasons for call audio degradation.

PVQA Test and Measurement


Sevana PVQA – Passive Voice Quality Analyzer is the tool that will help you with this task.
It is a unique powerful tool to non-intrusively (without comparing with reference audio file) evaluate voice quality by waveform analysis. PVQA MOS is perhaps the most accurate compared to other tools that predict MOS score by single file waveform analysis. Tool performance and ability to work in real-time give companies an opportunity to develop their own voice quality testing solutions not being dependent on particular hardware and software. PVQA is available as a cross platform application or library for all main desktop and mobile operating systems. Keep an eye on call quality with sevana.biz

5G Mobile Test and Measurement

How well do you know your network?
Do you know that in a packet switched network you may not only rely on ITU-T G.107 E-Model MOS and R-Factor? There are lots of other issues that affect QoE of your subscribers besides typical metrics such as jitter, latency, packet loss, or RTT delay.
Learning about issues “inside” the call gives you a unique chance to detect the issues not necessarily connected with network KPIs.
Ask us how knowing about Silence, Audio gaps, Clipping, Echo and Noise will help you to increase callers satisfaction and prevent their complains.

 

IVR PVQA Test and Measurement

AQuA perfectly suits IVR systems testing when one has a reference audio (original quality IVR prompt) to compare with the recorded audio. But how to validate IVR prompt quality if there is no reference to compare with? However, there is a possibility to validate IVR prompt quality even without comparison by using Sevana PVQA. It is just the same way as one analyzes voice quality of call recordings, because PVQA can forecast a quality score by waveform analysis of a single audio file. Contact us to learn more!

AQuA IVR Sevana Test and Measurement

IVR prompt verification and IVR prompt test automation are quite common tasks, however, there is probably no particular tool to make it really easy. And this is because you might have not heard about Sevana AQuA.
General purpose of AQuA is to analyze quality of the test audio by comparing it with the reference of original quality. However, unlike other similar tools one can use AQuA for IVR prompt verification, because comparing different audio files will naturally result in low quality score. Using AQuA for IVR prompt verification you verify the prompt and test connection quality within the same test call.
