What Our Customers Say

I would like to take this opportunity to thank you for the outstanding training I received at the Clark County Sheriff's Department. I went through polygraph school in 1974 and used it for many years, but I found your voice stress analysis to be easier to use and more accurate. Again, thank you!

- John P. Fay, Sergeant (Retired)

We want to highlight the effectiveness of your voice stress analysis software and the good labor of this prestigious company, especially its group of psychologists certified by the International Society of Stress Analysts (ISSA). We use the VSA at the embassy of the United States of America.
