Current trends indicate that people and organisations are actually moving away from the traditional Polygraph test (the one made famous by movies), to the Voice Stress Analysis (VSA). Opinions do differ in terms of which method is better, but the industry is certainly moving in the direction of the VSA.

At iFacts we promote Voice Stress Testing as a means of truth verification as we believe it a more friendly test and if the truth be known 80% of people tested are innocent. 

Using this means of assessment is as reliable as traditional polygraph technology and like a polygraph is used for the purpose of “detection of deception”. The VSA does not take into account the tone or pitch of the voice it merely measures “micro-tremors” in the voice which are linked to the stimulation of the central nervous system when the questions are posed. As the body responds to the stress the muscles in the throat tighten and the basic frequency of the voice changes.

An additional benefit is that the VSA test can be done via phone.
