Threat Level has posted an intriguing interview with Russell Tice from 2006. Tice provides a better idea of how some of the sorting might have happened.
Tice: Say you're pretty sure you're looking for terrorists, and you're pretty sure that the percentage of women terrorists as opposed to men is pretty [small]. So you just filter out all female voices. And there's a way to determine whether the signature of the voice is male or female. So, boom, you get rid of 50 percent of your information just by filtering there. Then from your intelligence work you realize that most terrorists never talk more than two minutes. So any conversation more than two minutes, you immediately filter that out. You start winnowing down what you're looking for.
Q: Without really knowing what it is you're looking for?
Tice: Right. And if you can develop a machine to look for the needle in the haystack and what you come out with from having the machine sift through the haystack is a box of straw, where maybe the needle's in there and maybe a few bonus needles, then that's a whole lot better than having humans try to sift through a haystack.
Sounds like a pretty easy system for determined terrorists to game.
