PLAN 4003 - VOICE STRESS ANALYZER

How many times have you wished you could tell if a person was lying? This is the best type of lie detector available as it needs no physical connection to the subject. It will work off of telephone, tape recording or from the next room via mic or bug. The analyzer monitors the subject's voice patterns and electronically evaluates their relative stress patterns to determine true or false responses.
