The proven alternative to traditional polygraph testing
The technology identifies various types of stress levels, cognitive processes, and emotional reactions that are reflected in different subtle properties of the voice.
This information provides insights into the way your subject thinks, what troubles him, what excites him, what portions of his speech he is uncertain about, what questions require more of his attention, and what areas appear to be sensitive issues for the speaker.
The technology is based on a proprietary set of vocal parameters found through research to correlate with key human emotions, and in various combinations to be able to identify deceptive intentions in “real life” scenarios.
The technology was originally invented in 1997 by Amir Liberman, and has been progressed over time in consultation with experts from different relevant fields including psychology, criminology, phonetics, psychiatry and mathematics.
