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. We also believe genuine high-tech can compete on merit, so we have never feared the competition. You can follow our work on LinkedIn.
Our story
Our path has followed one idea: get voice quality right, then prove it on real traffic. In fact, each milestone below moved us steadily closer to that goal.
- 2003Sevana is founded in Finland with an international team and a focus on sound quality.
- 2009We introduce our first sound-quality evaluation technology. Soon after, our first major client builds an automated call-quality monitoring system on top of it.
- 2015We release a technology that remains unique today: it uncovers the facts behind call quality, faults and lost quality of experience through comprehensive waveform analysis of real speech.
- TodayWe stay international, keep shipping new technology, and remain ready for whatever the market brings next.
What we do in voice quality analysis
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. In addition, around that core we build practical products for every workflow:
AQuA
Full-reference and no-reference audio quality analysis for labs and testing, benchmarked against POLQA and ViSQOL.
PVQA
Passive, perceptual voice quality analysis that scores live or recorded speech without a reference signal.
VQ Monitor
Real-time, passive VoIP and VoLTE quality monitoring across carrier networks, with dual MOS and alarms.
Pcaptix
VoLTE and VoIP call-quality analysis straight from PCAP captures, with dual MOS, timelines and AI explanations.
