Google introduces Vocal Captcha for Blind Users

Google introduced the Word-Verification CAPTCHA feature to prevent automated spam robots from abusing the system. The problem was that blind readers can't read what's written on the screen. Sometimes, the individual letters are so distorted that normal web users can't figure out the answer text.

Google now has a solution. If you can't read (or don't want to read) that cryptic letter CAPTCHA, Google has launched an alternat Audio CAPTCHA as part of their word-verification process. Users can click the accessibility wheel chair icon and it spells out some numbers. Listen and type the numbers you just heard.

The Voice Captcha is currently available when you sign up for a new Google Account but expect it to be available for Blogger Comment soon.

If you are not aware, CAPTCHA is an acronym for "completely automated public Turing test to tell computers and humans apart", trademarked by Carnegie Mellon University.
