THE NEW PSE®
5128
For over 40 years, the Psychological Stress Evaluator™ (PSE®) has been known worldwide for being the most superior system for lie detection. ONLY Dektor® invented PSE® and Voice Stress Analysis® in 1970. Nobody else! Only the PSE system of Voice Stress Analysis has been proven complete for reliability, effectiveness and validity. For determining truth or deception in criminal cases, employment screening and for all types of psychological evaluations, only PSE® will do the job.
In 2004, the PSE analog instrument was redesigned into digital technology. The PSE hardware was converted to software on a CD. The CD program is easily and quickly loaded into any PC: laptop, desktop or netbook. Any operating system, XP or later will work. Just a few simple steps are needed to load the PSE 5128. The computer can still be used as before. A security key is provided and must always used to prevent unwanted users access to the stored files. In case the computer is lost or stolen, nobody can access the stored lie detection cases. Dektor still provides a very high quality recorder to record the interview, mike, stand, special cables and the security key. Anyone who used the earlier PSE models (PSE 1, PSE 101, PSE Dek, PSE 2000, PSE 4202), knew how easy PSE was to learn and to use. The PSE 5128 is even easier to use. There are two PSE 5128 versions: 5128 RR and 5128 M.
The 5128 provides the same fantastic accuracy that has made the PSE famous worldwide for over 40 years! A recording is still made of the entire interview and kept for 10 years for review or as evidence, such as if a confession was obtained. Without the recorder, important details or a confession would be lost. Some law enforcement departments still rely on the old type of written confession by a subject. Courts and juries usually reject written confessions as not trustworthy. Using the PSE system, a judge or jury can hear a recorded confession in the subjects own voice and words. That will always win the case. Polygraph, computer polygraph and imitation “voice lie detectors” do not use a recorder. They suffer greatly because of that.
A top quality recorder is always provided with each PSE 5128 system. A high quality microphone is used to get the best sound quality of the subject’s answers for charting. The PSE software prevents distortion of patterns. Imitation “voice lie detectors” do not have that. Because of poor quality software, imitation “voice lie detectors” will have their chart patterns distorted and the examiner could come to a wrong conclusion. There are other new changes on the PSE 5128. For example, on older PSE models each verbal answer of the subject had to be charted using many steps. The PSE 5128 eliminates that. The taped recorded test questions and answers are transferred into the computer by a cable. At the top half of the PSE 5128 computer screen are rows of answer boxes. There are 65 answer boxes that can be used. At the bottom half of the computer screen, the Raw Voice Data is displayed. The Raw Voice Data is the recorded information that was entered into the computer. Each answer of the subject is “clipped” by the examiner from the Raw Voice Data. The clipped answers are automatically stored and charted in the answer boxes. The examiner can display each answer in various sizes and in different ways for an in-depth analysis. A change to the patterns appearance is done with just a click of the mouse and can be preserved. You can compare the various patterns to each other. You can also enlarge a small part of the pattern or stretch the pattern out for superior evaluation. Patterns can be displayed on the computer screen or printed out on any computer printer. No more buying expensive rolls of chart paper like on earlier PSE models. No more replacing those expensive chart printers or the heat stylus needles. All cases can be stored as files in the PSE program and recalled already charted. All questions and answers can be heard at any time after they have been entered and stored in the computer. The examiner can type in various types of information to be stored, including his name, subject’s name, date, type of case, test questions and their answers of yes or no.
Narrative Analysis is a exclusive feature of the Dektor PSE system. Any audio recorded or videotaped statement, of any length, in any language, overtly or covertly can be evaluated to determine truth or deception. On older PSE’s models, for Narrative Analysis, each word had to be entered manually into the PSE and then manually charted. That was very difficult and time consuming. It also made Narrative Analysis very expensive for the client, such as insurance companies for insurance fraud cases. Many times, with the earlier PSE versions, words were not able to be charted because the speaker’s volume was too low on the tape recording. Missing words could influence the outcome of a decision. PSE examiners in the private sector lost a lot of business because customers thought the prices were too high for Narrative Analysis. That high cost excluded many other types of clients. The PSE 5128 eliminates that. The entire statement can be entered and the charting of the words is quick and simple for precise evaluation. The examiner can type in the word for each pattern and place it anywhere near the pattern he wants so he can read the sentence and see the patterns at the same time. Evaluation is a lot easier and completely accurate. Manhours are reduced dramatically for Narrative Analysis using PSE 5128. That makes the cost less and the service is far more affordable to more types of clients, such as airports for passenger screening for security reasons and for insurance companies for insurance fraud. This ability is used at different types of security checkpoints in other countries and by insurance companies around the world.
The PSE 5128 comes in two great versions: 5128 RR and 5128 M. Anyone that used the earlier PSE models can INSTANTLY use the PSE 5128. No additional training is required to use the 5128. The Operations Manual to use the PSE 5128 is only about 7 pages for both PSE 5128 versions. That proves the PSE 5128 is very easy to learn and use.
Dektor®: the ONLY name that invented PSE® and Voice Stress Analysis™ for truth verification detection.
