Voice Stress Analysis

Voice Stress Analysis is a type of lie detector which measures stress in a person’s voice. That makes it recordable, and means it can be used on tape recordings older than VSA technology itself is.

Voice Stress Analysis from the National Enforcement Investigation Agency is a state of the art truth and deception system for detecting stress in the spoken word. Our examination when used in conjunction with a certified trained voice stress examiner, has an accuracy rate over 96%. Examinations are derived from clear and concise protocols that are time tested. Contrary to popular myth spread by polygraph users, several studies have shown the accuracy of this technology. We do not make any inconclusive calls on any examination like that of the polygraph.

Our examinations are non-intrusive and take approximately 90 minutes to complete. The examination consists of a interview, pre-test, examination and a post review. A detailed report is completed for each examination explaining the results.
