Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

I'm blind, and I'm Italian too, and yesterday I tried 20 times (more or less) to pass the "human check" to post a question. And what was the result? NOTHING!

So my question is: are there some tips to skip the check?

If the answer is NO, did you think about changing the check to implement logical questions? Something like:

How many letters does the word "Paperino" contain?


What is the result of: 6 for 3 plus 2 minus 20?


EDIT: Wow. On this site, the human control doesn't exist! The problem is on Stack Overflow.

The human control appears only from time to time, you don't get it on every post. – stema Nov 29 '11 at 8:58
Have you tried the audio version of the captcha? – balpha Nov 29 '11 at 9:01
He's blind. I suspect he only uses the audio version. – Ladadadada Nov 29 '11 at 9:59
Well, I tried obvously the audio challenge... – Filippo1980 Nov 29 '11 at 10:06
emh... sorry for my last comment but the screen reader doesn't love JS (and this site use JS too much), ok I was saying that I have an extension for Firefox (webvisum) and it should traslate the capcha challenge but in this site it doesn't work! Uff... – Filippo1980 Nov 29 '11 at 10:12
Webvisum now works properly! My suggestion still remanins! – Filippo1980 Nov 29 '11 at 10:18
The human check is fairly rare, however I get it on UX.stackexchange a couple times a week. I'd say I get it once a few dozen posts. This still sounds like a significant accessibility issue however and I don't know if/how our captcha program handles accesability – Ben Brocka Nov 29 '11 at 15:01

We use Recaptcha standard, same as millions of other websites. Recaptcha has audio for blind users, it's the little audio icon. See for yourself at

Per the (Google owned) service itself, as stated on the home page

  • Strong security
  • Accessible to blind users
  • 30 million served daily

It sounds like per your comment, this was an issue with a browser extension.
