Celebrity Voices
The voice behind Apple Maps is actually Siri, and while you can choose from a few different voices, it’s a system-wide change that affects Siri everywhere on your iPhone.
On the other hand, Waze not only offers its own selection of different voices, but can actually have your directions read by any one of a number of celebrity voices that you can find in the app or in online celebrity voice packs, including such classics as Morgan Freeman, Shaq, Stephen Colbert, Jay Leno, Arnold Schwarznegger, and even C-3PO.
