The Spion Portable Lie Detector claims to use voice tension to indicate true or false, and we’re totally implacably convinced that it works perfectly. Yep, there’s absolutely no question that this elegant looking device, with a picture of a devil with an elongated nose as an indicator, will tell you with unerring accuracy whether someone is telling the truth or not. Guaranteed, oh yes, totally. $79.95. Oh and by the way, we’ve got this bridge….
The Portable Voice Lie Detector is the first hand-held voice tension detector. Portable Lie Detector is destined to be the most talked about new novelty product this year. The portable device 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 isnï¿½t 100% accurate but after extensive testing, the Voice Lie Detector was shown to have a very high accuracy rate.
