NITV Federal Services' Computer Voice Stress Analyzer (CVSA) has quietly replaced the polygraph at nearly 3,000 law enforcement agencies, making it the most widely used truth verification device in law enforcement.

Among the nearly 3,000 users are the Illinois State Police, the California Highway Patrol, the California Department of Justice, the California Department of Corrections, the U.S. Federal Courts Division of Probation, and the police departments of Atlanta, New Orleans, and Kansas City. The Illinois State Police use 11 CVSAs, Atlanta police use 13 of them New Orleans police use 29, the California Highway Patrol uses 32, the California Department of Justice uses 10, the California Department of Corrections uses 58, and the U.S. Federal Court's Division of Probation uses 15.

According to these and other agencies that have made the switch, it's due to the CVSA's accuracy, low cost, and ease of use. Besides the normal use in criminal and background investigations, they also cite the CVSA's ability to analyze old taped interviews to help solve cold cses, such as a 37-year-old cold case homicide in Coles County in Illinois.

Law enforcement interest surged following the release of a study in The Journal of Child Sexual Abuse that found the CVSA to be above 96 percent accurate. The study found that 100 percent of voice stress analysis stress-indicated examinations resulted in verifiable disclosures of victims and sex crimes.

The CVSA is also being used by U.S. military special forces units throughout Iraq and Afghanistan. The CVSA was also very successful at the U.S. naval base in Guantanamo Bay, Cuba, where it was used to screen terrorists captured on the battlefield.

"From our special frces to law enforcement agencies...this is an investigative tool that has proven itself invaluable both on the battlefield and here at home in the criminal justice system," said Chad Jeansonne, legislative director for the National Association of Computer Voice Stress Analysts.
