CVSA and other Voice Stress Analysis Applications CVSA and other Voice Stress Analysis Applications
Computer Voice Stress Analysis--another pseudoscientific form of "lie detection"--is used by some law enforcement agencies as an alternative to the polygraph.

medical reasons
My question is are there any medical reason a person can't take the CSVA. I know that epileptics can't take a polygragh test. I was wonder whether or not if it's the same qualifications for the CSVA.
