Hi Donald,

Both Gez and David made good points. It seems pretty good to me, the
quality of the audio is good.

A couple of ideas. I wonder if there is a way of using more high level
words that can be understood more quickly by the screen reader user.
For example if the user was given the first few random characters in the
normal fashion and then a simple word that they would recognize and
could therefore fill in the rest themselves. So for example if there was
audio CAPTCHA output like  '1 2 sweet' it would have several advantages
1) it would be quick and  2) would allow the user to lookahead, as such,
and 3) provide a bit more security (in that it is not completely a high
level English term) but a combination of numerical characters and a
simple word.

This would mean the user could anticipate what is required without
having to wait for the entire digit by digit audio output to be readout.
They could then focus on any fiddly widget manipulation they need to do
to get it to work.

This could maybe used in conjunction with some simple question type
CAPTCHA asking something like Mary married John. Mary is Johns _________'

The more I look at this it seems like a lot of work just to keep the
robots at bay. Roll on better spam killing server bots!
