Truth Verification

    The Computer Voice Stress Analyzer or CVSA, is a state-of-the-art computer that processes changes in the voice and graphically displays a picture of the voice patterns. Utilized by federal, state and local agencies around the world in criminal investigations and counter-terrorism operations.

    Our CVSA examiners are certified and have over 25 years of experience in both public and private sectors conducting CVSA examinations. 

    Our Computer Voice Stress Analyzer (CVSA) uses only a microphone to capture a person’s spoken words. The instrument then analyzes the person's responses and allows our examiners to detect whether the responses were truthful or deceptive.  

    Drugs do not affect the results of the exam, and there are no known countermeasures to cause inconclusive results associated with a polygraph.

    Our examiners will use the CVSA to conduct the appropriate test for each situation and provide a detailed report of the results.
