Spion has rolled out the first hand-held voice tension detector called The Portable Voice Lie Detector. This portable device utilizes voice tension technology to measure varying degrees of vibration in the voice, which are good enough to reveal whether or not a suspect is calm when answering interrogation questions. So here’s how it works, each time someone tells a lie, the devilish figure’s nose on the screen will grow and his horns will appear. The greater the tension in the voice, the longer his nose and horns will be. Quite simple don’t you think? This portable device will set you back $49.95. [Product Page via Red Ferret]
