Find that fibber! The Portable Voice Lie Detector – the first of its kind – uses voice tension technology to measure varying degrees of vibration in the voice. These vibrations are caused by a person going from a calm state to a state of nervousness. Like when he rolls in at 3 a.m. and tries to climb into bed like you won’t notice. Uh huh. That’s when you whip out the Portable Voice Lie Detector and grill ol’ Pinocchio about his recent activities. That’ll show him. Or scare the sin out of him. Either way, you win.
