Abstract
This article provides background information on Voice Stress Analyzers (VSAs), including discussion of the theories which form the basis for their operation. The manufacturers’ claims regarding their ability to detect deception are evaluated in light of reported scientific studies testing the accuracy of the machines. A beneficial side effect to the use of such devices, regardless of their actual ability to detect deception, is reviewed. This article then reviews the position as to the use and admissibility of VSAs taken by courts in reported decisions from across the nation in a variety of legal proceedings.
