Lie detectors are sometimes too cumbersome too carry around and they do look very conspicuous to others. Hence, others will easily know when you carry the apparatus. However, Spion has just launched its new portable voice lie detector in the form of a hand-held device. You will surely like this. It would be a great fun to simply use it to catch your friends (those consummate liars) lie shamelessly to you.

This lie detector would measure vibrations in the voice associated with the user that would detect the change in the movement from a state of calm to a state of nervousness that is seen commonly when lying. The portable lie detector is similar to polygraph testing, which is not 100% reliable but has a high degree of accuracy. There are some advantages of this portable lie detector.

By virtue of it being small, you can easily carry it and conceal it simultaneously. The unit can also interface with a mobile phone. Apparently, the accuracy is even higher when the testing is performed over the phone. It’s interesting to note that every time the subject lies, the horns and nose grow. This is quite fun!
