What is the difference between Voice Stress Analysis and a Polygraph?

Voice Stress Analysis or Voice Stress Detection is the “new” polygraph of choice for those wanting to use digital, state-of-the-art AVSAPRO technology for lie detection or Detection of Deception (DOD). Truth verification testing is widely used across all industries for incident testing, honesty screening and pre-employment testing.

We operate from Midrand into Johannesburg, Pretoria and Gauteng and beyond.

Voice Stress Analysis / Detection measures “micro-tremors” in your voice using non-invasive (no electrodes attached) technology to produce conclusive results in lie detection and truth verification.

Voice Stress Analysis / Detection differs from the over-exposed polygraph in that it uses non-hostile techniques, in which there are no known counter measures to “beat” the test.

Voice Stress Analysis is safe to use and is not affected by drugs, alcohol, age, or existing health conditions.

This less invasive approach puts the subject at ease and leads to better testing.
