the google link works just fine.  one thing they do is repeat the string 
with the word again before the second itteration.  I also like their help 
for screen readers which provides a way to deal with a human being in case 
of last resort.

Did the embedded player work at all (did it play a sound, but the controls
didn't work) If so, we can just hide the actual controls. We may be able
to implement a "play again" button.

An example of this is:

http://google.com/accounts/NewAccount

Does that page's captcha work any better.

That button is a fallback. Nothing more, nothing less. Was the button
easily discoverable even though it was inserted behind the "switch to
audio " button in the dom?

Also, how was the experience finding that button (eg the tab order issues
we've commented about)
