Now how in god's name does a company claim they have an instrument that can detect mental countermeasures through the use of a microphone? Talk about snake oil. These companies are making fortunes off of agencies that believe this shit works.
your right , but lafayette is a well known company in the polygraph comunity as well for the computerized ones. Thier countermeasure method seem's to be something similar to voice stress analizer which measures a certain part of your voice when your deceptive.. This method is more garbage science thann regular polygraphyyy

I can see how the CVSA claims to "work", but this machine is being marketed to specifically detect mental countermeasures by somehow using voice analysis (if I am understanding their marketing hype correctly). CVSA uses voice analysis to try and indicate deception, but I have no idea how voice analysis could indicate countermeasure use!!!
Kinda reminds me of the X ray vision glasses you used to be able to order out of the back of Mad magazine as a child. Sounds too good to be true.
