PSE Computerized Voice Stress Analysis Systems:
The PSE instrument detects, measures and graphically displays the degree of presence or absence of inaudible body tremors that are superimposed on the human voice. These tremors disappear according to the amount of stress that is present at the moment of utterance. The interview and tests are recorded by the computer or cell phone. To do a test, the PSE examiner asks the subject various questions. The PSE technology filters the vocal answers, creates patterns and displays those patterns on the screen. The PSE examiner evaluates the patterns for truth or deception.
