I don't know how I turned it on but it's starting to bug me to no end. I'm noticing this in adium. Whenever the window is out of focus and I receive a message, someone reads it out. When someone connects it says connected. Haven't noticed it in any other program. However I turned adium's volume to zero but still have the problem. I even tried uninstalling/installing it and even upgrading to the latest beta.
I think it is a OS X setting that I've changed but can't get back. MSN messenger and Fire messenger don't seem to have this problem. I also checked accessibility settings and "voice over" is off.
help will be appreciated.
