[WSG] Accessibility : Turing/CAPTCHA test

[Nick Lo]

A while ago I brought up the topic of the Turing/CAPTCHA test on forms 
and whether it restricted accessibility on forms. The general opinion 
was of course that it does.

I just found this article:
"My article about Turing Protection generated lots of comments about 
how using image CAPTCHAs restricts access to the visually impaired.

So, I’ve played around a bit, and added an audio component. If you 
can’t read the CAPTCHA image, you can listen to a .WAV file of our 
lovely server, spelling out the characters to you."

Clearly as the author says it has it's limitations but in spite of that 
I thought it may be interesting or useful to some.
