Since iOS 8.1 Siri stopped working for me. The sound and wave animation appear, but it seems the microphone does not register my speech, or it is not processed by Siri.
I have read various "solutions" and tried to troubleshoot it, but I am running out of ideas.
I have tried, turning Siri on and off again :), restarting the phone and resetting different settings (including the network settings). Nothing seems to work.
Any ideas, how can I resolve this?
