What people have been trying to say, Joel, is that the audio captcha used there has changed and is more difficult to understand than it used to be.

An accessible captcha solution that does not take into account the needs
of the deaf-blind is no acceptable solution at all.

Cal,

I guess you've never before encountered a CAPTCHA of any kind? If so, sorry.
The topic is discussed on the blind tech support lists frequently, so I
didn't imagine this was a new and unpleasant surprise for you. The Audio
Challenge? I don't remember it being called that on CL, but maybe they've
labeled the audio CAPTCHA like that recently or I never noticed.

Anyway, what I'm trying to figure out is if you're experienced with this
sort of thing but you're complaining that the CL one just got weirder, or
it's just the first time you're encountering one of these and it just is too
hard for you to make sense of. Which is it? I'm not being unsympathetic,
please understand. I just want to figure out where you're coming from.

As far as making the characters Jaws friendly, I tried to explain in my
recent post that the reason the characters are *not* HTML text that anyone,
sighted or screen reader user, can recognize, is specifically because the
misshapen characters are meant to defeat automated programs using optical
character recognition (like what Open Book and other OCR program use) to
read them. As I said, the audio version is supposed to be a helpful
*alternative* to the visual one. When they call it a challenge, I don't
think they mean it to be challenging anyone but automated bots trying to
break into their system. They aren't intending to challenge you, too!

Sorry.

The audio challenge is too garbled for me to understand.  I just went to
EBay.com and they have the same thing.  E-mailed CL, but don't expect a
response...

So, if they make the text readable with a screen-reading program, that would
also make it easy for spammers to pick up with their automated programs?
Just trying to understand this concept.
