Stress Analysis of Voices

I remember when voice stress analysis first came into common use.  It was regarded as more accurate than polygraph tests for figuring out if someone is lying or not.  This appeared on the CBS Atlanta local news broadcast, and it does incline me to want a bit more proof than just Bialek's claim.

I would hardly call it conclusive proof that Cain is telling the truth and Bialek is lying, but this is certainly one more piece of low-quality evidence in Cain's favor.
