    • Voice Stress Analysis is simply used to validate the truthful, not to persecute the guilty. However our exam process is done by some of the finest investigators to ever use this technology, and the technique is paramount to achieving good results. Yes sometimes that also means identifying the deceitful among us if that is your goal.

    • With VSA's versatile examination process our examiners can identify the autonomic or involuntary response in your vocal cords, and spoken frequency deviations.

    • There are no known counter measures for the autonomic responses recorded by VSA. Alcohol and drugs are also not a factor in these exams, and they can be conducted in any language either LIVE, or COVERT boosting a 98% accuracy rating.

    • Law Enforcement at every level City, County, and Federal have employed these techniques for over 20 years. The US Military has been utilizing this technology since the 60’s when it was known as PSE (Psychological Stress Evaluator) as well as currently as an interrogation tool in the Iraq and  Afghanistan wars on terrorism.
