That's a cool idea, but they'll still have to provide an audio CAPTCHA for blind users, which is easy to solve.

Wow, I could barely make out the audio captcha!

A lot of spam operations use humans to solve captchas, so this isn't much of a change for them (actually could make it easier for them).

Wow, that's incredible how much noise they've added. I couldn't make it out myself. Its bordering on unusable IMHO.

Still, I wouldn't be surprised if a computer could get 1 in 4, which is plenty to be effective. They're still only using the 10 digits for the signal.

I have implemented something similar called "Visual captcha", where the user has to pick the cat out from 6 randomized Flickr pictures. The code is freely available and should not be hard to integrate into your own projects. Read more on: http://amix.dk/blog/viewEntry/19338

Also it's sometimes used as porn-bait (i.e. enter captcha to enter the "free" site).

Human solving is pretty cheap too. I've heard quotes about $2 for 1000 captchas. I guess with 1 click instead of 5-7 letters + enter - it's going to be cents per thousand soon enough, cause you don't even need to know keyboard well or type fast enough. So, I'd say that might be a step backwards.

can't someone figure out an anti-spam method that doesn't require a captcha? I mean its not like captchas even work, I'm yet to see one that works 100%
