Audio CAPTCHAs Cracked; ReCAPTCHA Remains Strong 157
Falkkin writes "Ars Technica reports that audio CAPTCHAs consisting of only distorted digits or letters can be easy to crack using machine learning techniques. This includes most of the audio CAPTCHAs currently in use on the Web. The reCAPTCHA team has discussed their new audio CAPTCHA, which is resistant to this attack."

I don't really understand how translating from speech into text is equal to translating from speech to text in a different language.
I could listen to every word you say and write it down no problem, but ask me to translate it into Japanese or something and I wouldn't have a clue.
You only have to look at games like Endwar to see how good speech recognition has gotten, it requires no calibration (well, maybe a word or two at the start) and has yet to fail me once and it seems to work for people with many different accents.
That said, Endwar does use specific commands so I suppose it could be a somewhat simplified scenario in that if the command words are selected sensibly there is no overlap in commands sounding nearly similar, but regardless even much of the voice reconigtion software for dictating documents etc. out there now does a great job with little to no training now.

It's already been done:

But good luck getting an invite. Users are pretty careful who we give them to. Also, I'm pretty sure webvisum sends the contents of every single page you visit with the extension on to the webvisum servers. So it has privacy implications. It's probably only worth it if, like me, your choice is between having no privacy or having no ability to solve CAPTCHAs.
