LEWES, Del., March 11, 2014 /PRNewswire/ -- According to the National Association of Computer Voice Stress Analysts (NACVSA), an organization that represents over 2,000 law enforcement agencies globally, a US federal court has ruled sex offenders can be required to submit to Computer Voice Stress Analyzer (CVSA) examinations as part of their post-release supervision. Northern District of New York Chief Judge Norman A. Mordue ruled the technique is analogous to polygraph examinations, which have been accepted by the 2nd U.S. Circuit Court of Appeals as a way to monitor the activities of those under post-release supervision.
Testimony before Judge Mordue indicated that some 1,800 law enforcement agencies in the United States have the devices available. Most have been manufactured by the National Institute for Truth Verification Federal Services (NFS), a West Palm Beach, Florida company that has been producing the systems since 1988, and is the acknowledged world-leader in voice-based truth verification technologies and training with three voice-based US Patents.
Interest in the CVSA by government agencies worldwide has increased dramatically due to a recently published peer-reviewed research study in the 2012 annual edition of the scientific journal "Criminalistics and Court Expertise" which reports the accuracy rate of the CVSA exceeds 95%, an assertion long made by law enforcement users of the system.
Further, a recently released book, "The Clapper Memo" by investigative journalist and author Bob McCarty, provides details about the efforts of the US polygraph community to remain relevant based on the worldwide success of the CVSA.
A Department of Defense survey of US law enforcement users of the CVSA reported that 86% found the CVSA to be either "very" or "extremely" accurate. The DOD survey also found that the vast majority of deceptive results with the CVSA were validated by obtaining confessions, and that the CVSA had "a very small error rate" - less than ½% according to the survey respondents.
Major US law enforcement agencies such as those in Atlanta, New Orleans, Nashville, Baltimore, and Miami, as well as the California Highway Patrol, depend upon the CVSA to investigate criminal cases as well as for screening police applicants. "As an investigative and decision support tool the CVSA has proven itself to be invaluable to law enforcement," stated Lt. Kenneth Merchant, of the Erie, PA Police Department, who serves as the Legislative Affairs Director for the NACVSA.
