There is a setting in there where you can change the speech from long mode to short mode. It significantly reduces the time to accomplish whatever function you're trying to use.
Before I found that she spoke way too much!
Plus I really miss the old iDrive where you could say "Call Sally work" and it would work every time. Now it's "phonebook", "call Sally" "entry two"..
A step in the wrong direction if you ask me.
