I have Snow Leopard 10.6.8. This has happened to me many times. I don't know why the circle surfaces, but the common response is false - in my preferences, Speakable items is set to OFF. Turning any of the Speech settings on or off does not make the circle window disappear. The only way I can get rid of it is to reinstall the operating system from scratch (not an update), which is an incredible pain. I've done this twice to get rid of the circle, and it's back again! This is clearly a Snow Leopard bug, since all the responses say when you go into preferences you should see that Speakable items is set to ON, and it's NOT.
Seriously, if ANYONE knows how it gets in this state, and how to get rid of it when it's not responding to preferences. Force Quit doesn't see it. Maybe there's a low level Console way to kill the app - I'd do anything to get rid of that circle...
GUYS - SNOW LEOPARD USERS! I SOLVED IT! I SOLVED IT! I still don't know what triggers it, but here's how you get rid of it without a reinstall:
1) Launch Activity Monitor in flat mode
2) Look for a running task called something like SpeechRecognitionServer and select it.
3) Hit the Quit Process button on the upper left!
Voila, that annoying circle is gone!!! 🙂
YIPPIE!

P. S. I just noticed that this bug still wasn't solved in Lion, so hopefully my solution will help Lion users as well. This bug definitely didn't exist in Leopard.
