The original VSA technology was devised by three former US Army personnel from the Counterintelligence Electronic Div. The three, Bell, McQuiston & Ford, developed the PSE 1, an analogue machine. The same three, working under Dektor Counterintelligence and Security Inc., manufactured the Phoenix telephone analyzer, the PSE 1000 and later the PSE 2000.

In 2001, the company X13-VSA Ltd. has released his first VSA product X13-VSA PRO Cobra (including a unique high-quality IVSA process) which is used today by the Italian State Police and the International Crime Analysis Association.

The National Institute Of Truth Verification (NITV, West Palm Beach) then produced and marketed an analogue instrument based on the PSE & digitized it in April 1997, based on the McQuiston-Ford algorithm. In the past 10 years VSA has been used primarily in digital applications: The primary suppliers worldwide are: NITV(USA)-CVSA; POLYVSA(TVT Centre RSA)- AVSA PRO 1_7KT & 2_0AG, Truth & Deception Technologies -DecepTech; Expertos and PSE 5128. ( Deceptech markets software previously known as Diogenes Lantern.)

The primary use of VSA is in the arena of "Detection Of Deception". As with the polygraph, manual VSA technology is inert and has no artificial intelligence component. However, the advent of AVSA PRO introduced Artificial Intelligence into the DOD arena. AVSA PRO utilises a neural network ( a training database) that relies on the input of VSA expert scoring. AVSA PRO eliminates common examiner errors and incorporates inviolate timing delays to enforce homeostasis and to make provision for the Onset Delay of the FOF syndrome.

The use of the recorded data as a means for lie detection that remains controversial. However, there are well-document cases where confessions were obtained after DoD devices indicated stress that led to confessions by suspects that were later definitively proven innocent. In civil court testimony, the CVSA founder testified that "NITV acknowledges that the CVSA is not capable of lie detection and specifically cautions its users regarding proper use of the device."
