Nope.

On new, standard PC equipment including external Dell speakers with volume controls, I was only able to hear two of the three words and thus, I assume, would not have "passed" the captcha.  Seems very unusable to me - having full range of hearing and corrected vision, good typing on full keyboard, all the advantages. The background noise was definitely an issue.

Thanks for posting. I find this very interesting.

This is an example of an audiocaptcha from ReCaptcha I recorded from the site TrueTwit yesterday:

http://audio.anysurfer.be/audiocaptcha_reCaptcha_truetwit.mp3

Can you understand it?

The reason I mentioned Mollom is because they use the phonetic alphabet (Alpha, Beta, Charlie, Victor, ...), which is cristal clear, and don't add background noise.

Kind regards,

Gijs

I've heard good things about the accessibility of ReCaptcha: can anyone comment on whether this is true?

Dear Maggie,

Mollom (http://www.mollom.com<http://www.mollom.com/>) is the most accessible audiocaptcha I know of.
I recently put up a WordPress blog with the Mollom captcha for test purposes:

http://gijs.anysurfer.be/wordpress/

Put the word "SPAM" in the commentfield and submit the comment to trigger the captcha.

Kind regards,

Gijs

Hi all

Does anyone have an example of a website where a  Captcha implementation  is done well, in terms of accessibility.

Much appreciated

Maggie
