Investigation Focus Tool

LVA 6.50 is a professional investigation focus tool using Nemesysco’s proprietary Layered Voice Analysis technology. It is capable of detecting and measuring many different psychophysiological reactions that are indicative of changes in the tested party's perception, alerting the trained operator to follow its indication and leads.

Layered Voice Analysis (LVA) Technology

Nemesysco’s LVA technology enables a quick and effective decision-making process based on any available human speech data. LVA identifies various types of stress, cognitive processes and emotional reactions that expose the emotional profile and sensitive discussion points of your subject.

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.
