According to the National Association of Computer Voice Stress Analysts -- an organization representing more than 2,000 law enforcement, security and military agencies worldwide – nearly 1,900 U.S. law enforcement organizations have made the systems switch. Among them are the police departments of Atlanta, Nashville, New Orleans, and Miami, the California Highway Patrol and many state and federal agencies.
"This is due to the low cost, ease of operation, adaptability, and high accuracy rate of the CVSA." It said. "Additionally, the old polygraph has been discredited at the highest levels of government because of its many high-profile failures ...."
The organization said that according to the journal "Criminalistics and Court Expertise," which reports the accuracy rate of the CVSA, the system's accuracy exceeds 95 percent.
NITV Federal Services, headquartered in West Palm Beach, Fla., is the manufacturer and sole source of the CVSA with the Final Analysis Confirmation Tool, a patented and validated automated scoring algorithm for quantifying and evaluating voice stress analysis patterns and charts.
