For many years, cvsa examiners have stopped using cvsa. They realized there was no accuracy or reliability to nitv’s cvsa and training that was any better than tossing a coin, about 50%. Instead of contacting Dektor and getting the PSE and our training for lie detection, the ONLY proven system of Voice Stress Analysis and training for lie detection, they bought other extremely unreliable “voice lie detector” gadgets, such as vipre. Vipre is sold by former executives and training instructors from nitv who wanted to “strike it rich” like they saw their former boss did with his cvsa scam. By all indications, vipre is still using the extremely flawed cvsa software program and nitv’s made up ideas for training lie detection.
I am an old cvsa user and have found out that the vipre is far superior in every way. The training at vipre actually explains chart Interpretation in a way that makes sense. "

I was a certified cvsa examiner and now, after certifying on the vipre, I can say I am utilizing the best available to law enforcement."
Coming from the cvsa training and equipment I am happy and proud to tout the vipre. Worry-free training and equipment is the key."

Vipre systems has streamlined the application of Voice Stress Analysis and is more effective and much more accurate than the cvsa I was accustomed to in the past."
Having used the cvsa in the past, the vipre is much easier to use. I now have a better understanding of the voice and chart interpretation as the vipre training is much better than what I experienced at nitv. The vipre is much more user-friendly and the technology is much more advanced than the cvsa.

The vipre system is much better than the cvsa in every way and the chart Interpretation training is much better than what I was taught in the cvsa class.

Vipre is without a doubt the best vsa on the market. I know, as I used to be a cvsa examiner."
