OpenDNS is for everyone. And by everyone, I mean everyone; moms, dads, kids, nerds, jocks, etc. We recently found out that our use of a CAPTCHA meant we were excluding blind and visually impaired people from using portions of our service. Thanks to some quick coding by Cory, we had an audio version of the CAPTCHA launched to solve the problem.
I was surprised at how easy it was to implement and I’d encourage anyone who uses a CAPTCHA to consider offering an audio alternative. There is a huge population of Internet-savvy blind and visual impaired users on the Internet who are well worth your time and effort to accommodate. If you want help with doing this on your site, we’d be happy to show you how we did it.

Hey David!
I’d like to recommend recaptcha.net to you!! It is really great, as it not only includes an audio captcha, it is also really hard to crack and it HELPS LIBRARIES etc. digitalizing their content!! That’s the kind of reason, why I really like it and am so enthusiastic about it, that I recommend it everywhere I can!
Please also mail me a feedback, if you might plan to implement and/or promote it!
PS: I have no connection to recaptcha.net, just a fan! ^^

I and many other blind and visually impaired people appreciate the implementation of an audio CAPTCHA on OpenDNS, and we certainly echo the belief that all sites should strive to make their visual verification schemes accessible.

That is the reason because I’m increasingly fan of you.

Another solution to create a Captcha with audio for your site can be found at http://recaptcha.net/ (© 2007 Carnegie Mellon University).
It can be included in most web sites and they have a WordPress plug in as well…
The audio alternates male and female voices and adds some background noise so that it becomes hard for robots to analyze and abuse the Captcha-protected forms.
Best regards,
Joe.

Hi, thanks for raising this on your blog, gives me a good link to post to people who don’t implement audio versions on their websites, and thus makes it impossible for us blindies to sign up to the services!

I also vote for doing some good work recaptcha.net
It does audio as well as helps translates books for the blind.
