      A investigation by the Air Force Research Laboratory in Rome, N.Y., for example, said that voice-based lie detectors ''do recognize stress through voice analysis. Voice stress analysis (VSA) and computer voice stress analysis (CVSA) are collectively a pseudoscientific technology that aims to infer deception from stress measured in the voice. The CVSA records the human voice using a microphone, and the technology is based on the tenet that the non-verbal, low-frequency content of the voice conveys information about the physiological and Promoters of pseudoscience: Andrew .

    6 Explain the research that has either proven or disproved the CVSA Note NITV from CMRJ at American Public University. Voice stress evaluation can help in the detection of deception or truth. Quite similar to a polygraph. In voice stress evaluation is used in investigation cases where the truth is most definitely needed. Voice stress evaluation is often more accurate and useful than polygraph, but polygraph can and is often used in combination with voice stress.

    He conducted briefings to end users and administrative level personnel on the development, evaluation and use of technologies including Voice Stress Analysis. He was Senior Analyst for the Air Force Research Laboratory, Rome, NY (AFRL) Evaluation of Voice Stress Analysis Technology, Phase 1 & 2, validating VSA and the Baker stress pattern.   Photo by Joe Angeles / WUSTL PhotoThe Truster hand-held "Emotion Reader."Voice-stress analysis, an alternative to the polygraph as a method for lie detection, is already widely used in police and insurance fraud investigations. Now, however, it is being touted as a powerful and effective tool for an array of new applications — everything from screening potential terrorists in the nation's.

The value of voice stress analysis technology' for military application could be extensive. During military field interrogations of potential informants, it could be applied in a manner similar to its application for law : Darren Haddad.

Research Laboratory (AFRL/IFE) for assistance in evaluating voice stress analysis technology. This evaluation is broken down in three phases. In the first phase, Dr. John H.L. Hansen, from the University of Colorado, investigated the feasibility of detecting stress from speech.

If voice stress can be detected, perhaps it can be taken into account in applying voice recognition technology and be used to improve these recognition capabilities.

Therefore, this effort is to determine the scientific value and utility of existing, commercial voice stress analysis technology for law enforcement and military by: The value of voice stress analysis technology' for military application could be extensive. During military field interrogations of potential informants, it could be applied in a manner similar to.

Theory Behind Voice Stress Analysis While most vendors of VSA technology omit specific details on how their systems work, by studying the basic literature, key information can be extracted on the theory behind the technology. Voice stress analysis originated from the concept that when a person is under stress, micro-muscle tremors (MMT).

Abstract: The Air Force Research Laboratory (AFRL) has been tasked by the National Institute of Justice to investigate voice stress analysis (VSA) technology and evaluate its effectiveness for both military and law enforcement applications. This technology has been marketed as commercially available in computer-based form, and marketed as being capable of measuring stress and in some systems.

Studies Validating the Voice Stress Analysis technology. Air Force Research Laboratory, Rome, NY, October, Funded by the National Institute of Justice, a three-year study by the AFRL determined that voice stress analysis achieved an accuracy rate of % when used to detect stress in 45 known-conclusion responses.

Voice Stress Analysis is a developing technology that can aid in the detection of deception. The underlying principle of VSA is that lying causes most people to experience involuntary psychological and neurological changes that occur at the subconscious level.

38th Hawaii International Conference on System Sciences, IEEE. Janniro, M.J., and Cestaro, V.L. ( Award-winning neuroscientist Marigo Stathis worked with Chapman to review and confirm the scientific validity of the resulting paper, which they entitled “Field Evaluation of Effectiveness of VSA (Voice Stress Analysis) Technology in a US Criminal Justice Setting.” Their research served to verify the effectiveness of Computer Voice Stress Analysis (CVSA®) in criminal investigations, with a focus on the usefulness of this technology.

Discussions about the application of voice stress analysis have focused on whether this technology can indeed reliably detect stress, and, if so, whether deception can.

The evaluation concludes that the two VSA units do recognize stress through voice analysis; however, although these systems state they detect deception, this was not proven. This study does show, from a number of speech-under-stress studies, that linear and nonlinear features are useful for stress.

The use of polygraphs, voice stress analyzers, and forensic testing in sensitive areas, such as the questioning of suspects in criminal cases, recruitment processes (e.g.

by the FBI), investigation of insurance fraud and interrogation of current or .Voice Stress Evaluation. The voice stress technology operates on the principal that the human voice has two frequencies.

When a person is under high stress or lying the frequencies change and that causes micro tremors in the voice. The plus with voice stress analysis is that the persons being tested does not need to be present. With this.
