Voice Stress vs. Polygraph - whats different?

[Goober12]

I may be going up against a Voice Stress Analysis test in a few months.  I am a bit confused what the difference is between Voice Stress Ananlsis and a polygraphgraph test.

Any and all comments welcome.

Many thanks

Goober12,

Well first of all, download, "The Lie Behind The Lie Detector", read chapters 3 & 4, and pay close attention to the parts on the CVSA. The polygraph parts apply for you too, as the CVSA is just another type of polygraph. Even though more worthless then the polygraph. Our resident polygraphers will even tell you they give the CVSA no valid worth what so ever. The key thing to remember on the CVSA is that it has been completely discredited as a deception detection device.  It can not tell if you are being deceptive what so ever. But its good to play the game with the operator so it looks like your being earnest. Much success to you.

The Lie Behind the Lie Detector does not address CVSA or other voice stress analysis techniques. However, as I've mentioned before on this message board, the behavioral countermeasures described in Chapter 4 of The Lie Behind the Lie Detector may be helpful for passing a voice stress analysis "test," too.

The polygraph purports to detect deception by comparing physiological measures as respiration, heart rate and blood volume, and perspiration as an examinee answers a series of questions. Voice stress tests purport to detect deception by analyzing subtle changes in the voice that are imperceptible to the human ear.

Neither voice stress "tests" nor polygraph "tests" have any scientific basis. In both cases, the machine is essentially an interrogational prop used to dupe the gullible into making admissions/confessions. The so-called National Institute of Truth Verification, which markets CVSA, has even admitted in federal court that their device "is not capable of lie detection."

For more about voice stress analysis, see the CVSA and other Voice Stress Analysis Applications forum on this message board. In addition, if you'd like to receive a PDF file with the CVSA operator's manual chapter on pre-employment testing, e-mail me at maschke@antipolygraph.org or give me your e-mail address through a private message on this board, and I'll be happy to send it along.
