Truth Verification


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

Criminal & Civil Lie Detection

The application of voice stress analysis in criminal complaints has been proven very beneficial for the prosecution, defense and client.  The examination can be utilized as part of the defense, and can also verify their client’s story.  Voice Stress Analysis can be utilized for any criminal case.

The use voice stress analysis in civil matters has proven to be invaluable.  In cases of insurance and workman’s compensation fraud, proving a false claim may save hundreds of thousands of dollars.  Many times during the examination process, admissions and/or confessions have been obtained, in turn leading to the dismissal of the claims.

Pre-Employment Screening


The goal of pre-employment examination is to verify information and statements that an individual has given in an effort to obtain employment with an employer.  Unfortunately, many unsuspecting employers have hired individuals with what seemed like impeccable credentials only to be embarrassed when unfavorable information is discovered.  An astute examiner can identify possible concerns and will usually obtain admissions that may, in and of themselves, deny them access to positions of authority.

Audio & Video Analysis


Examinations can be conducted on both audio and video recordings.  As with the live, one-on-one examinations, statements made on the recording can be analyzed as effectively as the other structured examinations.


The analysis of audio and video recordings from court records has be competed with great success.  Examination findings may be used in appeals cases and may be vital in obtaining new trials in cases where a person was wrongly convicted of a crime.
