These 2 lie detecting programs for PC will help you determine the truth from all the lies

The truth is that people lie and sometimes do it quite efficiently, which is why organizations are keen to identify deception. Although there are lots of technologies that have been developed to determine if a person is lying, most experts agree: no foolproof method of lie detection exists. This is saying a lot: since the early 1900s, experts have tried everything from measuring the changes in one’s blood pressure to linguistic and voice analysis, and many other methods.

Voice analysis

Usually, lie detection software uses voice analysis solutions: layered voice analysis able to identify various types of stress levels, emotional reactions and cognitive processes reflected in the subject’s voice. Researchers found that the frequencies of the human voice are sensitive to honesty. For instance, when someone is being honest, the average sound in that range will generally be below 10Hz and will be above 10Hz only when dishonesty is prevalent.

All the muscles in our body, including our vocal chords, vibrate in the 8 to 12Hz range. This is usually considered a feedback loop and is similar to a thermostat/heater that maintains an average temperature by oscillating between higher and lower temperatures. In that same way, our muscles tighten and loosen to maintain constant tension. When we are stressed – telling a lie, for instance, and not wanting to get caught – our body prepares for fight or flight by increasing the readiness of its muscles to spring into action. The vibration will increase from the relaxed 8 to 9 Hz to the stressful 11 to 12 Hz range.

Such vibrations are a measure of stress levels that will change from one moment to another. You surely know by now that stress can be brought up by a mere memory. Some people have average stress levels while other people have low levels. What they all have in common is the fact that their stress levels change all the time within their current range.

Usually, the lie detection software for PCs looks for shifts in the voice and can turn out to be very reliable truth verification tools.

Lie Detector Software eX-Sense – Voice Stress Analysis

Through voice alone, the tool can determine whether your subject has any doubts, what exactly is troubling them in a conversation, and if they are sincere. With its help, you can turn your computer into a polygraph you can use to analyze live conversations and interviews using your computer microphone.

Phone conversations are straightforward to interpret because of their quality, and recorded phone conversations will offer you the opportunity to take your time for a more sophisticated analysis. You can also find out who is telling the truth on recorded or on live television. You should know that digital TV offers great quality, perfect for analyzing lies and deception.

The tool uses the Sense Technology, one of the most advanced technologies in the world for voice analysis. It uses Layered Voice Analysis to listen to the minute changes that occur in the human voice. Sense is able to analyze different layers in the voice while also providing an in-depth view into the subject’s range of emotions. The tool’s technology is a poly-layer voice analysis that users more parameters gathered from each speech segment.

Its VoiceGraph technology is tuned in a such a way to expose extreme emotional situations that are usually associated with lies and deception. The VoiceGraph analysis is displayed on a single bar that will change its color from green to red according to the emotional intensity associated with lying. This makes it extremely useful for recorded conversations. The tool also uses VoiceGraph to judge the likelihood of deception and this feature better makes it helpful for analyzing an ongoing conversation.

The tool also includes something more: a Love Detector mode! The Love Detection voice algorithm is the result of four years of studies and research.  You can finally make sure your new relationships are on the right track. Find out how interested the other party really is!
