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.
