Cost Savings

Requires minimal training time, so law enforcement officers do not have to be away from their assigned duty for an extended period of time. The lower cost of our training benefits the agency's budget, without compromising the quality of training.


Voice Stress Analysis (VSA) technology can also be used in covert operations since an individual's verbal responses can be recorded and analyzed at a later time. The use of voice stress analysis in a hiring process has proven invaluable for pre-employment screening. The pre-employment examination is utilized to assist background investigators with fact finding and the verification of information presented by the applicant.
