Some info about used methods: this application uses Voice Stress Analyzis method for realtime lie detection.
Voice Stress Analysis (VSA) technology is said to record psychophysiological stress responses that are present in human voice, when a person suffers psychological stress in response to a stimulus (question) and where the consequences may be dire for the subject being tested.
Air Force Research Laboratory (Haddad et al.) conducted validation studies into VSA and concluded that mainstream VSA as well as polygraph tests are useful in helping trained operators in obtaining confessions by convincing the subject that they cannot deceive the device. As such, it is considered a useful interrogation tool.
There is tension between the voice stress analysis community and the polygraph community, due in the main to the fact that the polygraph is heavily regulated and has been subject to numerous detailed, contentious scientific studies, while voice stress analysis is largely unregulated. However, there are few studies which show VSA results to be even slightly better than chance.
VSA is based on the presence of infrasonic components of human voice not audible to observers, caused by a physiological phenomenon present in muscles called "microtremor". It was discovered in 1957 by British physiologist Olaf Lippold. Further investigation by other researchers explored the possibility of the presence of microtremor in the muscles controlling the voicebox (Larynx.) The experiment was made by attaching electrodes to the cricothyroid muscle and the posterior cricoarytenoid muscle and measuring EMG signals.
