Will the same CM's used to avaid false positives on ploygraphs produce tremors in one's voice to work on the CVSA?

There is no reason to expect that they would, and there is no evidence that they do.

I once had the opportunity to experiment with a CVSA-equipped computer. I found that as I repeatedly said "No" into the microphone, while not under any stress at all and not actually answering any question, the computer reported that I was "deceptive" about one-third of the time. Go figure.
