About Voice Lie Detector Prank

Find out which friends and family are honest and which are liars!

WARNING - This is not a real lie detector as such a thing would be impossible to put in a phone, but it's great fun for parties.

Simply ask your friends and family a question you want to know the truth about, record their answer, and let this miraculous app tell you just how honest they really are.

This app will record any sentence or question you record and then send it through our state of the art algorithm which analyses a myriad of factors in order to give you the truth.

Great fun for parties and gatherings and an invaluable tool when you want to see just how well you know the people closest to you! (This is not a real lie detector as such a thing would be impossible to put in a phone, but it's great fun for parties!)

How to play:
Press start, have someone say something into the recorder, press stop, and the app will analyze the sentence and tell you if it is true or false! It can also be used in a question/answer format where you ask the question, record someone's answer, hit analyze, and let the app tell you if their answer was true or false!

Lie detection, also referred to as deception detection, uses questioning techniques along with technology that record physiological functions to ascertain truth and falsehood in response. It is commonly used by law enforcement and has historically been an inexact science. There are a wide variety of technologies available for this purpose. The most common and long used measure is the polygraph, which the U.S. National Academy of Sciences states, in populations untrained in countermeasures, can discriminate lying from truth telling at rates above chance, though below perfection.They added that the results apply only to specific events and not to screening, where it is assumed that the polygraph works less well.
