Polygraph and Voice Stress Analysis Truth Verification

The sure way to know for sure!

We Are Based In Nelspruit But Do Work All Over The Lowveld And Swaziland

The more I see, the less I know for sure.” ― John Lennon

Since humans have learned to communicate we have learned to lie to each other. The search for the truth and the quest to find a means by which we can test the veracity of people’s stories, is as old as mankind itself.

As we have such a plethora of different people lying, many scientifically based techniques have developed. These range from the analysis of the body language (kinesics), facial expressions, statement analysis (SCAN) as well as Psychophysiological Detection of Deception (PDD) – Bio-feedback Polygraph  and Voice Stress Analysis (VSA).

The VSA or Voice Polygraph system is a fully automated system that provides accurate results with a less than 1% error probability. The sure way to know for sure!
