​What about the Computerized Voice Stress Analyst test (CVSA)?

To date, the AAPP has found no scientific studies or independent research which support voice stress analysis as a method of discriminating between truth and deception. In fact, the most recent study by the Department of Defense, completed in September 1996, concluded that there was "no credible evidence to validate voice analysis as an effective instrument for determining deception.

Ultimately, every procedure and process employed by a law enforcement agency must be able to withstand the in-depth scrutiny of judicial proceedings. In making a determination of acceptability, the courts will weigh the available scientific data. “Testimonials” without the support of reliable scientific (information will not meet the standards for acceptable evidence. Polygraph is the only deception detection device which has the scientific support and has earned judicial acceptance for expert testimony.

Additional information regarding voice stress analyzers may be found at the National Criminal Justice Reference Service.
