Remove "Folder Open" "Folder closed" announcements without disabling Accessiblity
Found a solution that worked for me.  From this page:


Go to Settings> Application Manager> All> Google Text To Speech Engine
Instead of disabling it entirely, hit "Clear Data"


Note: This solution may or may not be permanent (I have a feeling when I next actually use a feature with Voice, it will re-enable), but it's easily repeatable at need.  It's mostly viable for me because I don't use such features terribly often.  If you use Maps every day or whatever you might need to find a different answer.
