Scientists from Nizhny Novgorod Linguistic University have invented a non-contact lie detector - a computer program that determines the levels of stress and emotion through voice analysis.
While most polygraph tests work by attaching multiple sensors to a person's body, the program created by Vladimir Savchenko and Dmitry Akatiev simply records the sounding speech and immediately shows the results. It demonstrates if a person is nervous or scared even if he remains outwardly calm.
Moreover, even if a person speaks without an accent, the program can identify the country or region from which he is.
