I've had this crazy issue for several weeks now after doing a clean install of Yosemite from Mavericks. I hoped it would just go away like a lot of Mac quirks seem to do after an upgrade but no.
I notice it mostly when I type a tweet in YoruFukurou. I'll do command n for new tweet and start typing and VO says, "apple, submenu" over and over as I type so that I can't hear my keyboard echo. I have to command F5 toggle to make it stop.
At first I thought it was just YoruFukurou that this happened with but I've noticed it in other areas I type, even renaming a file in Finder.
I've tried opening the application chooser menu to see if there's some dialogue open and at first there was. But I've tried that again and there was no odd dialogue open and never anything that says "Apple, sub menu".
I am at a complete loss and this is incredibly annoying as it pops up with no warning, like when taking down a phone number in Text Edit when I'm on a phone call.
Has anyone seen this behavior and even better, found a solution? I've repaired permissions and that seems to stop it for a time but it always comes back. *scream*
Thanks a million.
