IF... IF the footage on that news spot really showed an actual CVSA unit (a laptop), then I sincerely believe that it does less than "novelty" voice-stress lie detectors that are merely sound level meters and blinking lights. The CVSA on the news did less. The voice patterns did not match what was being said, nor any [real, true, physically possible voice waveform], but apparently was just a random predrawn scribblewave "card" appearing on the screen.

And After getting his PhD in biblical psychology, he (the CVSA pusher) sold his soul and many others to the devil.

There is a very famous and powerful cult that uses tester-controlled "lie detectors" for brainwashing. Hint: John Travolta.
a false lie detector + a confession = a lie + a false confession detector

Once there were pocket calculators and you could count on them
to give you the TRUE answer to a Math question.
Now there are computers with worms, bugs, viruses, trojan horses,
porn, hackers, false advertisements, and demons in their brains!
What do you expect?
OF COURSE!!!
