The Academy for Scientific Investigative Training neither practices nor endorses Computerized Voice-Stress Analysis, Layered Voice-Stress Analysis and / or Voice-Stress Analysis by any other name

Polygraph testing should not be confused with Voice Stress Analysis.

Independent studies showed Voice Stress Analysis to be "almost as accurate as flipping a coin", and therefor the Academy for Scientific Investigative Training and its affiliates prefer not to be associated with this type of practice in any form.

Furthermore Voice Stress Analysis is not accepted at the CCMA.

If you start a career in lie detection, or truth verification, doing Polygraph training is the accurate choice.
