Ugh. Why is is that most captchas are a) illegible and
Thats the idea, after all, otherwise a simple bit of OCR would break them.
b) wholly inaccessible to the visually impaired?
Some do have an audio option for such users.
I've never understood what's wrong
with simply asking a question that only a human could answer correctly
(e.g. "What colour is the sky?")
Which could easily be defeated by a speech recognition system. So instead
the text sounds like it is being shouted by someone at the back of a busy
call centre. Its about the same level of difficulty to understand as the
visual version.
One such example is the msn registration (only had a look it was mentioned
in the register register), but not much use for here as NetSurf can't get
to the registration page to try it out.
