VOICE STRESS ANALYSIS
Voice Stress Analysis
At IPSC, we 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. Since independent studies have yielded that it is “almost as accurate as flipping a coin”, we prefer not to be associated with this type of practice in any form. Voice Stress Analysis is also not being accepted by the CCMA.
