Voice search is one of my favorite functions of the phone. Never had a problem with it. I have not downloaded any apps or updated anything in a week or so.
This morning I was in the map program and wanted to voice search something (in google, not on the map). But the search went on the Map. So I killed all my apps and restarted voice search. Now, nothing happens with Google voice search. I get the window that pops up with the microphone icon on it. Sometimes it makes it to the "working" screen but goes no further. Most of the time it just sits on the Speak Now screen and nothing happens. At first, I typically will see the "meter" showing audio, but sometimes it just does nothing. It just sits at the speak now screen. I never can get a result.
I have restarted the phone. Removed the battery and/or SD card numerous times. I've cleared data and cache on the Voice Search app. Not sure what else to do.
EDIT: BTW.. "Voice Dialer" works just fine. So it appears to be just a Voice Search issue.
