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. Other voice stress analysis products like Truster, Truster Pro, Handy Truster, and Layered Voice Analysis have also been promoted. But do they actually detect lies?
