Voice Stress Analysis application from Truth & Deception Technologies was originally used in determining attempts at deception in law enforcement activities. In the world today you may hear the words "lie detector" in reference to this type of technology. This type of technology actually detects deception in the human voice. Subsequently it's advanced user friendly capabilities found additional applications in determining deception in arson, counter narcotics, insurance fraud, employment screening, private investigation, anti-terrorism, interrogation, covert counter intelligence and the like.
Many agencies are currently using our voice stress analysis instrument for pre-employment examinations instead of old outdated polygraph machines. Achieving the latest significant advances in voice stress analysis since development of the Psychological Stress Evaluator (PSE). What we developed was a truly computerized voice stress analysis system, which takes full advantage of digital processing to give the examiner a new set of sophisticated, analytical tools. Operational DecepTech Voice Stress Analysis Systems have been delivered to law enforcement agencies in the United States and a host of foreign nations.

The DecepTech(tm) Voice Stress Analysis instrumentation is the most technically advanced digital Voice Stress Analysis system that has been produced. Our instrumentation is designed to detect, process and display changes in the physiological "Micro - tremor of Lippold" in human speech. The graphical waveforms produced and displayed by the instrument can be interpreted by trained analysts to reveal the relative level of voice stress present in the subject. Our instrument creates printed reports quickly and easily for the examiner's review and to allow cases to be documented and shared among other examiners. You can share the actual recorded interview with fellow examiner's when a backup call is warranted. Our voice stress analysis software can be easily used to analyze recorded interviews of any length and source. This opens up the possible applications of the software to include cold case interviews, informant interviews and other voice stress applications. You can easily record your interview in the field and later analyze the recording in the security of your office or remote location. Depending on your state, covert interviews are also possible.

Our software is Microsoft Windows(tm) compatible installing easily on any desktop or laptop computer. There is no need to dedicated a computer for only this application. Our software can be loaded on multiple computers for added convenience of the examiner.

Our training programs can be scheduled at our central locations or at your location. We offer mentoring after initial training, plenty of practice examinations, and assistance in creating protocols for your specific requirement.
