Audio "captchas"

Audio captchas when visual images are unusable via Official Google Blog

"Wikipedia defines 'captcha' as an acronym for "Completely Automated Public Turing test to tell Computers and Humans Apart" -- a word which is trademarked by Carnegie Mellon University. Most web users think of captchas as those hard to read distorted letters or images that one often is confronted by when websites attempt to verify that they're indeed talking to a live human. Google Accounts support captchas. Of course, bloggers (no matter which platform they use) can also use them to prevent comment spam."
