If you're obsessed with lie-detection as a hobby, and the Truth Detector and Jerk-o-meter are not enough for you, then the deFIBulator may round out your collection of truth detection devices. It's manufacturer, Spion, claims:

"After extensive research and development in labs in Singapore, Spion has developed the first generation of the DeFIBulator hand-held voice tension detector. The DeFIBulator utilizes voice tension technology to measure varying degrees of vibration in the voice. These vibrations are caused by the user going from a state of calm, to being a little nervous as you would when you lie. Even an F.B.I. polygraph isnŐt 100% accurate but after extensive testing, the DeFIBulator was shown to have a 65% accuracy rate. It can even be connected to your cell phone! As a matter of fact, because of the digital connection it will actually be much more accurate."

It's a game, of course; I don't think anyone really believes in the accuracy of casual truth metering. Afterall, lying is such a complex art and/or sickness, and really good liars lie mostly to themselves (can any device detect self-deception?). Once the DeFIBulator is "trained" to the subject's voice, Demonochio's nose grows and its horns appear on the screen when the subject lies (assuming the lying is betrayed by increased tension in the voice). I suppose you could also use it to practice lying.

Available at GadgetUniverse for 49.95.
