CAPTCHA is an acronym for "Completely Automated Public Turing test to tell
Computers and Humans Apart." They have been a burr in the backside for some
time. I am not sure if there is a universally acceptable solution yet, but
your idea of a simple question that a robot could not correctly reply to has
been suggested.

Here is a nice review of the issue dating back to 2005

You can also search through Google using the terms "accessible captcha" and
read some of the other articles about this.

I'm not sure what to do about the Twitter thing. I listed to the auditory
captcha and couldn't figure out what they were saying. Maybe Dennis Lembree
who developed Accessible Twitter has a solution - you can reach him at

Subject: [WebAIM] Captia/security boxes

Hi all,

I'm sure you're familiar with those stupid captia boxes, where you
must type the letters you see to prove you'r not a spammer. Most have
a "listen to this" option but I haven't even figured those out. I
tried to sign up for a twitter and could not get past their listen
option. It says to type the 2 words, but it gives me an entire phrase
when I listen. Does anyone know a work around?

Also, I've heard of some sites simply asking a question like, what
color is grass? If I were to write to sites that have these
inaccessible or confusing captias, might I suggest an alternative? Are
the open to that sort of thing? I had a sighted friend help set up
Facebook, and they have an option to reply to a text message to
eliminate further captias. This is great, but I needed a sighted
person to help set it up.

I'd like to get a twitter to see what all the fuss is about, but I'm stuck.
