The second operational mode of the system, the OFFLINE mode, let’s you perform a very in-depth and precise analysis on pre-recorded materials, so you can evaluate the suspects response and identify new leads that may have been ignored or over looked. Both modes of operation offer a very intuitive user interface, combining textual analysis with graphs and playback options to make the results as easy to read as possible.

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* (where applicable by law)

The LVA 6.50 Messages

LVA 6.50 can detected many different emotional reactions, and will display one textual message for each voice segment that identifies the most relevant / critical type of deviation from the baseline.  This way, when the system detects  no deviation, the message will be “Low risk”, meaning, nothing to suspect. Deviations in the excitement, stress or logical reactions will be titled “Excitement” “stress” and “Subject not sure” accordingly, and so on depending on the intensity of the reaction, more extreme messages may appear, such as inaccuracy, voice manipulation, and even High risk, indicating severe reaction and out of homeostasis.

  • Low Risk

  • Excitement

  • Subject not sure

  • Stress and High stress

  • Voice Manipulation

  • Inaccuracy

  • High Tension*

  • High Anticipation*

  • Medium Risk/High false probability*

  • HIGH RISK

* Messages available only in Offline mode

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.
