VOICE STRESS ANALYSIS

Lietech neither practice nor endorse 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. Due to the fact that independent studies have yielded that it is “almost as accurate as flipping a coin”, Lietech and its members prefer not to be associated with this type of practice in any form. Voice Stress Analysis is also not being accepted by the CCMA.
