The use of Voice Stress Analysis (VSA) for the detection of deception has become the preferred method to reliably detect stress.
The VSA is a technology that aims to measure deception from stress measured in the flexibility of a subject’s vocal chords. When the subject is put under stress, they will enter into a response to perceived threats. This causes the muscles in their throat to tighten, which has an effect on their vocal chords.
Used as an investigative tool, the technology differentiates the stressed and non-stressed outputs. The VSA is a much friendlier test in terms of how it interacts with the subject. It is important to remember that an employee cannot be dismissed purely as a result of a VSA Test. The results of these tests can only be used as supporting evidence when a case is presented at the CCMA.
