Publisher's description of Lie Detector

From Champion Software:
Lie Detector uses a sophisticated and accurate algorithm that looks at pitch, frequency, and peaks in the voice and compares it to calibration questions. Lie Detector gives you a frequency comparison of the person's truthful answers to the questionable one so you can decide how truthful they are being. When a person speaks they produce inaudible fluctuations called microtremors. When a person becomes stressed, physical changes such as increased blood flow cause the audio range of the microtremors to change. Lie Detector analyzes this change to determine how stressed, and therefore how truthful, a person is being.
