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are currently using voice stress analysis instruments for investigations and pre-employment examinations instead of old outdated polygraph machines.

In an attempt to demystify the subject it should be made clear right at the outset that there is presently no known instrument which can actually detect lies. If the label “lie detector” must be used, it is best attached to the examiner who interprets the physiological by-products of a tested person’s emotional responses, and by using various techniques in conducting the voice stress examination, is able to offer an opinion of truth or deception.

To gain the most benefit from this technology it is our opinion that the voice stress analyzer should never be used in isolation, but rather as an element of an overall intelligence-gathering program, or as investigative tool. Ideal proactive applications for a polygraph include pre-employment checks & applicant screening, statement verification, locating hidden assets, obtaining investigative leads, narrowing a list of suspects and obtaining evidence for use in criminal or labor courts.
