Sevana builds the voice quality analysis technology that measures how good a call really sounds. We have been international from day one: we started in Finland in 2003, continued from Estonia since 2010, and still run a team and partner network across the world. Above all, we believe genuine high-tech always has a chance to win, so we have never feared the competition. You can follow our work on LinkedIn.

Our path has followed one idea: get voice quality right, then prove it on real traffic. Each milestone below moved us closer to that goal.
In short, our voice quality analysis turns raw audio and packets into clear, defensible quality scores. Our perceptual engine, PVQA, listens to the decoded speech the way a person would, while our network model adds the transport view. Around that core we build practical products for every workflow:
Full-reference and no-reference audio quality analysis for labs and testing, benchmarked against POLQA and ViSQOL.
Passive, perceptual voice quality analysis that scores live or recorded speech without a reference signal.
Real-time, passive VoIP and VoLTE quality monitoring across carrier networks, with dual MOS and alarms.
VoLTE and VoIP call-quality analysis straight from PCAP captures, with dual MOS, timelines and AI explanations.
Because audio quality is all we do, our customers reach us for the hard problems other tools cannot explain. We work closely with each partner, we keep our roadmap open to their needs, and we stand behind the result. Therefore, operators, testers and software vendors trust Sevana when the goal is simply the best possible sound for their users.
“NetQPro has worked with Sevana for many years, extending our monitoring solution with their know-how in waveform analysis. Our customers value Sevana’s expertise in audio quality evaluation and the benefits it brings in troubleshooting. Especially now, as VoLTE grows, Sevana’s technology for end-to-end verification of voice services enables full, instant problem detection and reliable service. Moreover, Sevana has proven a professional partner, always open to close co-operation. Therefore, we recommend them with full confidence.”
