The Captcha Debate

In response to the following article, from the Inventor of the recaptcha

Interesting article, but Blind users cannot read captchas! and even for partials who use Window Eyes, Zoomtext, or the open source alternative NVDA, recaptchas are still near impossible to read for us blind folk.

We try the audio version, and the audio verson doesn’t match what their input box accepts. The audio version is hard to hear for those who are not sight impaired, but for those of us who are sight impaired, we can hear the numbers fine.  The problem is,  the numbers we hear in the audio captcha aren’t recognized as the correct string in the input field,  so we type in the numbers we hear, and its not accepted.

so the audio captcha is useless. and I find the same to be true for all the captchas out there in internet land… so the problem really isn’t solved, only worse, especially for us legally blind folks who depend on character recognition software to read us whats on the screen.

If your going to make an audio captcha,  write the code for the input box that accepts both the visual and audio versions of the captcha, and make sure it WORKS. Nothing more annoying then using an audio captcha that doesn’t work. LOL
