iOS Tip 171 - Announce Callers

Have your phoneannounce, out loud, who’s calling.  It’s cool, because if you’re making dinner or watching TV or something, you know whether it’s worth answering. “Call from Google Map,” it’ll say — a telemarketer — and you can ignore it. “Call from Capitol Macintosh” and, of course, you’dleap to answer.
The iPhone can do this too.
Open Settings > Phone >Announce Calls.  Here, you get to choose when the phone announces the caller’s name when it rings: Always, Never, Headphones Only, or Headphones & Car.
