The majority of the agencies preferred the CVSA to the polygraph.
(PRWEB) May 1, 2008
A little over twenty years ago, some of the best minds in voice biometrics began to develop the Computer Voice Stress Analyzer (CVSA) based on the original technology, the Psychological Stress Evaluator. Progress on the new forensic voice biometrics system was slow due to the stringent standards that the NITV used to validate their technology. However, this formula paid off as the CVSA is now relied upon by thousands of law enforcement agencies, including most major metropolitan police departments, and the US military. The automatic scoring algorithm utilized by the CVSA took ten years to develop and is known as the “Method for Quantifying Psychological Stress Levels Using Voice Samples” (patent # 7,321,855), was deemed so unique and accurate that it was recently awarded a patent by the US Patent Office.
This all began with the introduction of the CVSA to a largely skeptical law enforcement community in 1988. However, the CVSA was so successful at every department that acquired it that soon word of this tremendous investigative tool spread from agency to agency. Over the past twenty years nearly 1,800 agencies have acquired the system and tens of thousands of crimes have been solved, many of which had gone ‘cold’ and would never have been solved were it not for this unique investigative tool.
With the military’s Special Forces successes in Iraq utilizing the CVSA to obtain actionable intelligence on the battlefield, the CVSA has drawn the attention of William Shatner’s “Heartbeat of America Award” given to businesses that keep American strong. The show, to be aired on national TV in May, is a prestigious award NITV shares with such esteemed past recipients as “Doctors Without Borders.”
Nothing can keep America stronger than identifying those that would harm her. The threat that is posed by individuals that wish to destroy America is very real and very present. Besides being used by law enforcement to separate the guilty from the innocent and by Special Forces to identify terrorists on the battlefield, the CVSA has the capability of identifying terrorists at screening centers around the world and at all Ports of Entry. As chronicled by Washington Post, New York Times and other publications, this task has become especially critical since the quality of counterfeited documents has made it much more difficult to identify these individuals.
“The NITV has produced one of the finest tools available today for use in both the war on crime and the war on terrorism,” stated Chief Bill Endler (Ret.), former polygraph examiner, retired chief of police, and now a senior instructor for the NITV (chiefendler @ CVSA1.com). Chief Endler has conducted thousands of criminal examinations using the CVSA and agrees with the recent Department of Defense survey of CVSA users in which nearly 90% stated that the CVSA was either “Very” or “Extremely” accurate. Dr. Thomas Joseph (tjoseph71 @ cs.com), a veteran of 26 years in the criminal justice system, is even more enthusiastic, “The CVSA should be at every investigative agency in the US. It is a very quick, non-intrusive manner in which you can accurately screen through all of the clutter and get to the truth.”
In a study of the technology, funded by the Department of Justice and conducted by the US Air Force Laboratory, the researchers reported their findings to the 38th Hawaii International Conference on System Sciences. The Air Force study found that the technology “is a viable alternative to the polygraph.” Additionally, a “US Special Operations Command Independent Evaluation of the CVSA,” led by a Ph.D. researcher, found that “The majority of the agencies preferred the CVSA to the polygraph.” It also found that most of those agencies had discontinued the use of the polygraph. According to Chief Endler, “This was mostly due to the fact that countermeasures were very effective against the polygraph, the polygraph took so long to conduct, and the results were often inconclusive.”
According to Paul Hollrah, a writer for several publications who has investigated the issue extensively, the resistance by the Department of Defense polygraph proponents to the more accurate and versatile VSA technology is doing great damage to our national security by keeping it from the very people that need it the most – the war fighters.
In his most recent column, Mr. Hollrah writes, “One returning Special Forces interrogator has said that there are two principal reasons for the reduction in violence in Iraq: the surge and CVSA technology. It’s time that civilian officials in the Pentagon recognized what law enforcement officials across the country are proving every day: that CVSA technology can be the most significant tool yet available in our search for actionable intelligence in the War on Terror. The lives of our fighting men and women are at stake and it’s time the Congress demanded that the Pentagon tell us exactly whose side they’re on."
