With the new turn by turn directions from Apple’s new Maps app in iOS 6 firmware (coming fall 2012), the voice of Siri directs you where to go. I’ve found a problem with this. When I’m using Siri or voice to text to send a text, Siri will talk over me. What’s encouraging is she can understand herself. It’s kind of annoying but it would be nice if either; it wouldn’t let you use that feature when you’re close to an upcoming voice prompt, it would wait until you’re done, or shut off voice to text during the announcement. Here’s a couple screenshots of Siri’s directions being typed out by the voice to text feature.
