Silent Talker Lie Detector
The Silent Talker Lie Detector is an attempt to increase the accuracy of the most common lie detector, the polygraph, which does not directly measure whether the subject is truthful, but records physiological measures that are associated with emotional responses. The Silent Talker gives the evaluator access to viewing microexpressions by adding a camera to the process.
