Depends on the jurisdiction. No matter how you slice it's it's an interception, it may be a transmission (to the iPhone if nowhere else), and there is an argument to be made that the text extracted is a recording.
It is in no way settled law especially in places with 2 party consent laws like Florida or California. Nevermind Oregon. Or the Europe. A cursory search suggests France's laws have some teeth to them.
It also doesn't address the inadvertent listening problem.
