Tell Me No More Lies…Or Else!

The USPTO has awarded National Institute for Truth Verification (NITV) founder Charles Humble a second patent for his CVSA (Computer Voice Stress Analyzer) II. The CVSA II accurately measures voice patterns for stress levels and then rates the person being tested as having “No Deception Indicated” or “Deception Indicated.” Just what makes this device superior to polygraph testing in certain situations? Several aspects.
Firstly, the embedded software–which runs on a laptop computer–can be used to test live conversations, telephone conversations, or even recorded audio files. Also, with the new algorithm, Humble claims that “recorded audio is just as good as live audio.” And more than 1,800 federal and local law enforcement agencies, not to mention the U.S. military, recognize its value for helping catch criminals and use the CVSA II already.
A second benefit to the CVSA II is the fact it has a reported accuracy rating of greater than 96 percent. And since it allows for real-time or post-interview analysis and an evaluation of the entire exam, it does away with potential bias during the exam process.
Both the patents awarded to Humble for the CVSA II relate to the establishment of numerical values for stress levels associated with someone being deceptive. According to Humble, the device monitors the frequency changes and voice modulation whenever individuals are lying. “From the Atlanta P.D. to the Nashville P.D. to the California Highway Patrol, this is an investigative tool that has proved itself to be invaluable in the field,” says Alan Hall, operations administrator at the NITV and a former military intelligence officer.
The NITV claims that the CVSA II has helped bring tens of thousands of criminals to justice. A number of high-profile cases have occurred in the last few months. One particularly heinous case involved a Louisiana man accused of raping his son. The man was about to be released due to lack of physical evidence, but after being confronted by the results of his CVSA II exam, he ended up confessing to the crime. A second high-profile case involved a Utah man confessing to a brutal murder and providing the murder weapon to the police when also confronted with the results from his CVSA II exam.
“CVSA is much less complicated than a polygraph,” Humble says. “A polygraph uses a lot of squiggly lines that you do not necessarily know what they mean. This uses simple graphs that chart their stress levels.” Humble envisions a time when more people than law enforcement officials utilize CVSA technology in situations where it’s important to find out if someone isn’t being completely truthful.
Which just goes to show how important it is to patent those inventions just as soon as possible!
