We offer Computer Voice Stress Analyzer, which is conducted by a certified examiner. What is CVSA and how does it work?

The CVSA requires no wires to be attached to the subject being tested. It only uses a microphone plugged into the computer to analyze the subject's responses. As the subject speaks, the computer displays each voice pattern, numbers it and saves each chart to file. Unlike the polygraph, drugs do not affect the results of the exam and there are no known counter-measures that will cause the ubiquitous,"inconclusive" results associate with the polygraph.

The computer voice stress analyzer is effective in all investigative situations. Such as: homicide, sex crimes, robbery, white-collar crimes and internal affairs investigations, as well as pre-employment examinations.

Micro tremors are tiny frequency modulations in the human voice. When a test subject is lying, the automatic, or involuntary nervous system causes an inaudible increase in the Micro tremor's frequency. The CVSA detects, measures and displays changes in the voice frequency.

A state-of-the-art computer processes these voice frequencies and graphically displays a picture of the voice patterns. The CVSA is not restricted to "yes" and,"no" answers and is able to analyze accurately, tape recordings of unstructured conversations.
