No cheating: Russian scientists have developed a voice lie detector

Russian scientists have developed a lie detector that recognizes deception by a person's voice. A polygraph test was passed by the correspondent of the TV channel “MIR 24” Artem Vasnev.

“How old are you?”. “I'm four months old. Don't forget that I am a robot. “

They promised to show us the voice polygraph in this laboratory. While waiting for a specialist, we communicate with Irina, an assistant robot. She demonstrates her capabilities.

“Ready to take.” – “Take it!” – “What do I have in my hand now?”

Maxim Konobeevsky is the author of a voice polygraph. I have been creating the program for several years. It is now uploaded to the server. Parents can test their child, for example, for drug addiction. Employer – test the applicant for decency. A smart program reads lies from the vocal cords.

“Lying is usually stressful. A person is afraid of being exposed, and at the moment of lying there is a high cognitive or mental load. A lie needs to be invented, correlated with what you said before, what you will say later. And this stress leads to some psychophysiological reactions, ”explained Maksim Konobeevsky, director of science at a robot manufacturing company.

  Our subject is Stepan, a laboratory worker. He sits in a chair. The machine asks questions. Simple at first to compose a voice portrait.

  “Is this room dark now?” – “No”.

  Next, there is a line of questions that should disclose personal information. Does Stepan use drugs or not?

  “Are drugs no more dangerous than tobacco and alcohol?” – “No”.

  The result is ready in five seconds. On the laptop screen – diagrams.

  “According to the results of this test, there were suspicious answers. We do not say that our test subject is a drug addict, but when applying for a job, it was worth paying attention to, ”noted Maxim Konobeevsky.

  Stepan assures, he spoke the truth and only the truth. But where do the suspicious answers come from?

  “They are based only on knowledge.”

  It's time to test the system for yourself. The task is to deceive the robot. Adrenaline goes off scale.

  “Before testing, a so-called loringophone is put on the subject's neck. It is a device that reads voice readings directly from the vocal cords. Please”.

  Loringofon on me. The robot Irina will test me. Now let's see if I can deceive her. If you think about how to cheat, you are in a hurry. The robot immediately sees that the person is worried.

  “Are drugs no more dangerous than tobacco and alcohol?” – “No”. – “Error”.

  “Did I fail the test?” – “Yes, the number of errors has exceeded the permissible level.” – “Am I a drug addict and an alcoholic?” – “We cannot say.” – “What does my result say? That I failed the test? “You are not in optimal condition for testing right now. You need to calm down, accept this situation and respond slowly. “

  So it didn't work to deceive the polygraph. And this is impossible, the developers say. He was tested on prisoners. In particular, scammers. The clever car got it all right.
