I am having this issue now, I have tricked Cortana into listening briefly when using UK (opens bing) then switching back to US, she listens and the words begin to be typed, then its ignored and "I'm sorry i didn't get that" starts again.



I want to say the issue started yesterday for me. Shame it just quit on me.



Going to bing > settings > personalization > Other Cortana Data and Personalized Speech, Inking and Typing > clear, will that clear out my reminders, I refuse to redo the reminders I have set. There are way too many of them set. I read that this is a good way to clear the Cortana not listening issue for the pre release WP 8.1, unsure if this applies now.



HTC One M8 Windows Phone ATT.



Hope this just fixes itself or someone finds the fix, I have been fiddling with this since last night.
