Voice Lie Detector Services
What is unique about our technique? Our approach differs from other agencies in several significant aspects. We are the only ones to combine a vocal lie detector system with blood pressure readings and two channels of Galvanic Skin Response, which is the most accurate physiological measure of the traditional polygraph. By triangulating modalities, we can replicate findings and provide more accurate final judgments. Unlike other voice lie detector tests, we score not only the answers to 'YES/NO' questions but also longer narratives. This allows for a more comprehensive judgment of critical issues. Our method utilizes our proprietary voice stress analysis software within an algorithm that identifies critical diction and coherence structures for special coding and differential scoring. This additional analysis ensures the highest degree of accuracy. With staff trained in clinical psychotherapy, we can communicate results in a more empathic and intelligible manner than other testing services. We also provide very specific follow-up suggestions for further investigation or treatment, which is especially helpful when addressing sensitive family and personal issues.
Computer Voice Stress Analysis: What is a computerized voice stress analysis? Voice Stress Analysis is a method that measures subtle changes in vocal quality caused by the tension that often accompanies deceptive utterances. This tension arises from the autonomic nervous system and cannot be controlled or hidden by the person being tested. In fact, according to the Law of Inverse Effect, the more they attempt to control their responses, the greater the tension that will be detected by the vocal lie detector. Who uses it? Various versions of the voice lie detector test are routinely employed by government intelligence agencies, probation services, and law enforcement departments across the country. The Berkeley Police Department, known for its history with the polygraph, now relies on voice stress analysis software as a crucial investigative tool in major crime cases and employs it exclusively during background screenings for new officers.
