Layered Voice Analysis (LVA™) is Nemesysco’s core technology,
developed by Amir Liberman
LVA technology is based on a proprietary set of vocal parameters found, through field & academic research, to correlate with key human emotions and in various combinations to be able to identify deceptive intentions in “real life” scenarios. These vocal parameters were identified from a large repository of audio files captured in different languages and a numerous life situations, from police interrogations, through contact centers to controlled experiments. Many of the parameters Nemesysco’s technology uses, are new to the world of phonetics, and focus on the uncontrolled and, as yet, phonetically unexplained properties of the human voice.
LVA is a security-level technology designed to serve professional investigators in their line of work, by providing indications that further directs the investigation procedure to the relevant path. LVA analysis can be performed in real-time (using a microphone or on a telephone conversation) as well as off-line on previously recorded material. RA7 system is using the LVA technology in a highly controlled manner using scripted conversations, which enables the system to “understand” what emotional reactions are expected in each part of the call (as well as which emotional reactions are not).
