PSE Book

ONLY the PSE®, technology for Voice Stress Analysis™, training techniques and chart analysis procedures were invented only by Dektor® in 1969. Only Dektor’s complete system has been validated by the U.S. government for 45 years.

Only the PSE® and Dektor’s truth verification system had a 200 page book, independently published in 1980, proving Dektor’s system was completely valid for truth verification and psychological evaluations. NO other imitation “voice lie detector” or “computer voice analyzer” has that. The book is titled “Investigative Proof of the Reliability and Value of the Psychological Stress Evaluator in Science, Medicine and Law”. It was written by Mr. Michael Kradz. Mr. Kradz was a highly trained polygraph examiner, he was one of the founding members of the American Polygraph Association in 1965, he had a Master’s Degree in Psychology, and was former Chief of Detectives in Maryland. His very long and impressive resume can be read further down.

The complete book can be read on our website or you can order the book itself by contacting Dektor. The book is $100usd. The book is a must have to read and own by people who are serious about using the PSE and Voice Stress Analysis for lie detection.
