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.
