Totally anecdotal, but I thought I'd pass this on.

Whenever I use Goog 411 or Dragon, my results improve if I speak like a standard radio announcer. You know, that kind of jokey, fake lilting voice that they use on car commercials? I hate doing it because I sound like such an ass, but whenever I've done so, Google understands what I'm saying. YMMV.
