Raising the awareness of Web Site Accessibility and Marketing.
Dr. T.V. Raman posted to the Official Google Blog yesterday, explaining audio CAPTCHA’s and Google’s policy. While explaining the need to be accessible, he also asks for user feedback on the current methods being used by Google. (A trademark action by Google - getting user feedback)
Here’s your chance to let your voice be heard. Help Dr. Raman improve the accessibility at Google!
I often find myself staring at these captchas and wondering how to read them. Fortunately most sites are...
Everything is possible nowadays and we shouldn’t be afraid to use the technology that...
Hello. I do think captcha is a good thing because it can keep out spam and stuff of that nature. Ok lets say you...

Now, I give spammers a lot of (begrudged) credit for their ingenuity in coming up with ways to break CAPTCHAs, but breaking these types of questions would require some pretty serious AI. I’m willing to bet if a spammer could answer these questions, he’d be selling the AI, not spamming.
The bonus from using this type of method is that you don’t need expensive backend components to generate the images or audio. And, of course, since it’s text only, it’s accessible.

Dan, you’ve given an excellent example of the Turing Test approach to filtering who gets in to a net service.
But there’s a deeper problem I encountered when administrating a UBB-based forum last year. There are genuine humans who are (presumably paid) to join services for the express purpose of spamming.
