NOTE: Voice lie-detection is used by the California Highway Patrol,
the Los Angeles County Sheriff Department, nearly 200 California
police agencies, and nearly 2000 world-wide law-enforcement &
military agencies have used it including the FBI, CIA, NSA, NIS,
Homeland Security, Military Investigative Units and many major insurance
companies, often instead of the old-style polygraph examinations!

Insurance companies routinely use voice lie-detection to screen for fraudulent claims

From Wikipeda, a trusted and neutral source:

 "A great deal of voice stress testing (VSA) has been conducted. In the United States, some states do not
regulate the private use of these devices. However, the CIA and FBI both use VSA at times, in their own
investigations. The technology is currently recognized in 43 states. The biggest user of VSA technology in
the USA is US law Enforcement agencies. Law Enforcement agencies in Israel, India, Malaysia, South Africa,
China, Hong Kong, Poland, Russia, use VSA alongside polygraph.Many intelligence agencies as well as
private forensic pychophysiologists worldwide utilize VSA in preference to polygraph technology."
