VOICE STRESS ANALYSIS SERVICES      

Voice Stress Analysis (VSA) is a lie detection technology, which is newer than the polygraph.Based upon the interpretation of variations in involuntary nervous system responses, these results are not affected by any of the commonly believed negative influences on the results of similar techniques such as polygraph.  These results cannot be altered by any possible attempts of subjects to disguise responses. The primary use of VSA however is in the arena of 'Detection of Deception'.  In the past 10 years VSA is used primarily in digital applications. The purpose of a VSA examination is to determine the truthfulness of responses made by an examinee regarding the subject under investigation. Determinations are made by analyzing and scoring the voice-grams produced by the examinee. Traditional analysis of voice grams was achieved by allocating "percentages of stress" (%) according to the patterns so produced.

 

Devices used to analyze voice stress are usually used in the presence of the individual under investigation; however, they can also be used without his or her knowledge. Since all that is needed is a voice, a wireless microphone, a telephone connection, or even a tape recording can provide the necessary input signal. A great deal of voice stress testing (VSA) has been conducted. In the United States, most States do not regulate the private use of these devices. However, the CIA and FBI both use VSA at times, in their own investigations. The technology is currently recognized in 43 States.

Many Intelligence Agencies as well as private Forensic-Psycho physiologists worldwide utilize VSA in preference to polygraph technology.

SERVICES TRAINING AND EQUIPMENT

Not only in law enforcement and the judicial system, but also in the corporate world, this technique finds a useful role.  For example, it would be an asset to utilize this technique during the human resources hiring of employees for positions of trust and responsibility.  Companies providing Cash in Transit services, banks, recovery companies, security companies, the list goes on and on of those who benefit from this technology.

We can provide the complete system together with training and equipment, or, we can provide the analysis services ourselves where practical.  The analysis can be carried out remotely with transmission of digital data by commercial data services such as telephone or internet.
