Re: Does double announced content bother screen reader users?

Not a problem with a form field is announced twice by screen reader.
We can always shut them up.
There are problems with overly aggressive live region announcements,
but for duplicate announcements of static page elements, it is at
worst an annoyance.
Also, the screen readers themselves should sometimes be smart enough
to filter their communication, such as when an elements accessible
name and description are identical.
