The Tool of Choice for (almost) Any Investigation Need…

Unlike other systems of its kind, LVA 6.50 analyzes free and natural speech, and in fact prefers to “listen to the thought process” as it gives the LVA more voice data and helps to understand the thinking mood of the suspect – things that cannot be identified from a simple “yes/no” response. This feature makes it suitable also for undercover work analysis, when the analysis is conducted (where applicable by law) without the subject’s knowledge or preparation.

Analyzes free speech  |  Most accurate  system of its kind  |  Language independent  |  Doesn’t require the subject’s consent*

LVA 6.50 and the Polygraph, Friends or Foes?

Is LVA 6.50 a substitute for the polygraph? We say no.
The polygraph has been around for over 100 years, and when used properly it is a very effective tool. We have several polygraph experts in our network, and we can say clearly where each of the products can complement the other, all with the aim to get to the truth.

*​LVA 6.50 completes (not competes) with the Polygraph

  • Use LVA earlier in the investigation when you may have a large number of suspects and little time
  • LVA 6.50 is used in the pre-test interview (before the polygraph test), and can hint to prepare a better Polygraph questionnaire
  • LVA 6.50 works over the phone and with recorded material
  • Use LVA when you don’t want the suspect to know
  • Better with open conversations than with “yes/no” questions
