A report about Computer Voice Stress Analysis (CVSA) on the website of Central Ohio television station WBNS (“Tool Catches Fibbing Suspects”<\/a>) concludes by mentioning that the Special Forces are using CVSA to interrogate suspected terrorists in Iraq and Afghanistan. The entire report is reproduced here: <\/p>\n\n\n\n

More and more police departments in Ohio are turning to technology used in war zones to question suspected terrorists and to determine if someone is telling the truth.<\/p>

Critics call it “junk science,” but a central Ohio detective swears it turns suspects into confessors.<\/p>

When Detective Dave King walks into an interrogation room, he brings a secret weapon. It’s a computer that measures stress in a person’s voice.<\/p>

Detective King says the computer never lies. “These computers are now used in more than 140 Ohio police departments. At $10,000 a piece, they are actually a cost saver to departments that can’t afford a full time polygraph unit,” says King.<\/p>

Critics say the voice stress computer is junk science and officers are using trickery to gain confessions.<\/p>

10-TV Reporter Kevin Landers put the computer to a test.<\/p>

Detective King hooked a microphone to him, and answered two questions. One question he answered truthfully and one with a lie. King says the results from the machine tell him when Kevin is lying.<\/p>

King says, “There have been times when people come in and I totally bought their story.”<\/p>

Then he turns the machine on.<\/p>

“Had it not been for CVSA, I, and other investigators, would have believed what they told us and they would have gotten away with it,” says King.<\/p>

Voice stress analyzers are also in use in Iraq and Afghanistan. Special Forces units use them to interrogate suspected terrorists.<\/p><\/blockquote>\n\n\n\n

The critics who call CVSA junk science are supported by the National Institute of Truth Verification<\/a> (the company that peddles CVSA) itself, which has reportedly acknowledged in a court filing<\/a> that CVSA “is not capable of lie detection.”<\/p>\n\n\n\n

That the U.S. Government is relying on the junk science of voice stress analysis to interrogate suspected terrorists is corroborated by the testimony of a former Guantanamo detainee.
