My very thought.
I went out and bought a copy. Turns out it was for Windows XP/ME, and won't run on Windows. Better yet, MicroCenter wouldn't take it back...
So I bought a copy of Dragon Naturally Speaking instead.
Now the key with this type of software is that you have to train it to recognize your voice -- it can't just pick up a random voice from an interview. So I read JFK's Inaugural Address to it for a while, until it seemed to be picking up most of the words. Then I put on earphones, played an interview, and repeated what was said into the Dragon mike. It got about half the words right. I'm guessing that the pace of the interview was just too fast for the software, which advertises a transcription rate of about 160 words per minute. So that's why I didn't recommend that approach to my fellow volunteers.
Of course, if you have any further suggestions I'm all ears...
