Truth Detector - Stress Analyzer

The next hot gadget for discriminating job interviewers might be something like the Truth Detector.

It's not like the familiar old toys that pick out random answers. It actually contains Psychological Stress Evaluator (PSE), and Voice Stress Analyzer (VSA) algorithms which analyze the frequency changes that take place when a person undergoes stress. The machine's detections are then displayed through a bar graph using an LED band.

This is effectively a simpler version of the "Computerized Voice Stress Analysis" that police departments are adopting.

Unlike the "Truth Detector Watch", the person speaking doesn't know he/she is being analyzed.
