Thought you might find this interesting -- about Macromedia's choice to
make older Flash content available to screen readers, and how to work
around that.

Subject: RE: Inaccessibility of older Flash movies
Hi Steve -
Thanks for your comments. It's good to know that people are using our
accessibility support - even if this leads to problems!
The issues you're describing are typical for older Flash content that is
complex. We're looking at a retrofitting problem here: the content was
developed before we had accessibility support, and now it will take some
work to make the content accessible. This is a consequence of our
choice to try and interpret older content for MSAA. That choice
actually has great benefit for simpler legacy content - many Flash
movies just suddenly start working, without any changes. The downside
of this choice is that more complex legacy movies just cause a lot of
babble.
This kind of problem is not limited to Flash. Any complex website
designed before accessibility tools were available would be likely to
exhibit similar problems. Many modern DHTML pages fall into this
category.
There are certainly some problems with our accessibility implementation
- among these are some things that you mention, like dropdown support
and tabbing out of movies. The current Flash Player is really just a
first version of accessibility support, far from perfect, and we're
working on major improvements for the next release of the player.
But some of the solution to the larger problem you're talking about
(complex legacy content) must rest with content maintainers and screen
readers.
Content maintainers, at the least, need to take a quick look and see
what their biggest problems are. If those problems revolve around
excess verbosity, the near-term strategy is to disable screen reading of
the movie until there is time to put better accessible logic into the
movie (if that's even practical at all). You suggest a perfectly
reasonable workaround for this near-term solution: provide a skip-Flash
link. A slightly better technique that we would endorse is
re-publishing the Flash movie as version 6, and simply turning off
accessibility support for the whole movie (uncheck "Make Movie
Accessible" in the Accessibility panel while nothing is selected on the
Stage). This makes the screen reader ignore the Flash content entirely.
Screen readers, for their part, would do well to include a feature that
allows skipping past a section currently being read. This already
appears in the form of, for example, next-paragraph key bindings.
Perhaps a reasonable enhancement would be a
skip-past-current-Flash-movie key binding.
Also note that while some of the verbosity can come from the initial
reading of a Flash movie, a lot can subsequently come from animation in
the movie prodding the screen reader to re-read the page. Window-Eyes
has included a key binding to help users deal with this: if they press
Ctrl+Shift+F (I think - I might be misremembering the specific keys
there), Flash events will stop being sent, turning the page into a
static page that doesn't repeatedly start over from the top.
Thanks again for your input. We hope that our next version of Flash
will make enough improvements that everyone will be able to make their
content accessible without undue effort.
