PROFILES has spent thousands of hours (starting in 1977) researching and developing a Specific Issue Screening system (truth verification/lie detection) that will indicate whether or not a person warrants further in-depth evaluation.  HOW IT’S DONE…  The person first completes a short Specific Issue Questionnaire concerning an incident:  Crimes Against Property or Persons, Espionage, Terrorism, Smuggling, Rape, Murder, etc.  [There are polygraph examiners that utilize these questionnaires to psychological preconditioning the person  to be examined]. Next, this person is seated in front of the INTERVIEWER SYSTEM that consists of 2 tape recorders, a headset microphone, and a bank of interview tapes for various incidents.  We have also developed an extensive Pre-Employment Background Investigative Questionnaire (BIQ) for Law Enforcement and private security agents that is used in conjunction with the INTERVIEWER SYSTEM.

One tape player plays the appropriate survey tape and the other records the person's "YES" or "NO" responses. The tape containing the person's verbal responses is then processed through the Psychophysiological Voice Stress Analyzer (PVSA) computer.

The  PVSA computer  measures  how the  person emotionally reacted when answering. This numerical data is then analyzed by a computer program containing a special algorithm (1st copyright in 1982) where reaction patterns are compared to a known control group. 

Because of this unique survey and analysis technique, the Specific Issue Screening system cannot be “consciously” biased or “thrown” by the person. It also eliminates the possibility of analyst error. 

No other Voice Stress Analyzer system can match this system’s accuracy, reliability & versatility!!!

We have trained a number of Law Enforcement Agencies in the proper use of Voice Stress Analyzers utilizing proven polygraph techniques.
