Help with information about the voice analysis

[guandra]

Hello,

I work in a company that does investigation against insurance frauds, and I'm doing I'm looking for information about the voice analysis, where I've found the voice stress analysis and the layered voice analysis.

My first question is if there is another technology about the voice analysis and where can I find information about them?

The second question is related aboutt the companies that make the machines and that give the analysis service. It doesn't matter where in the world, what are the most known companies that make this technology and that give the service of analysing subjects? Until know I found DIGILOG and NEMESYSCO.

Thanks for your help

LVA (layered voice analysis ) is BS. It 'analyses' pitch and tone - aspects
that can be manipulated by the subject.
LVA = coin toss.
