BRIEF DESCRIPTION OF THE USE OF AN INSTRUMENT WHICH DETECTS SIGNS OF STRESS IN A SUBJECT'S VOICE DURING INTERROGATION.
Abstract
THE OPERATOR AND THE SUBJECT FIRST DISCUSS ALL QUESTIONS TO BE ASKED AND THEN GO THROUGH THE LIST, TAPING THE ANSWERS. THE TAPE IS PLAYED BACK THROUGH THE PSYCHOLOGICAL STRESS EVALUATOR, WHICH TRANSLATES THE VOICE FREQUENCIES INTO A PATTERN ON A GRAPH. THESE DATA ARE THEN ANALYZED BY THE OPERATOR FOR SIGNS OF STRESS.
