Blogger have only recently officially announced an audio option for word verification when you're trying to post a comment on a Blogger blog.
Maybe they were swayed by Kirk's trenchant rant about the impossibility of reading some of the squiggly stuff they put up there. But now, if you can't read the word verification captcha, you should be able to click on the little blue wheelchair icon next to the word verification box (why not a pic of ears though instead??)
- and it's supposed to read out some numbers to you, which you then type into the box, by playing a WAV audio file, so that you can login and publish your comment.
The only problem is, whatever they're using has a fair amount of background noise, and furthermore they're saying it a bit fast to type in one go, for me anyway - I have to listen to it at least twice myself before I can type it in properly. I mean, listen to this. Or maybe I'm just harder of hearing than I'd like... It's good that they've provided some further help for those who have trouble using the audio verification, but personally I think the best thing to do would be to eliminate the background noise and have the numbers read out more slowly, myself.
Nonetheless, it's obviously a good thing that they're trying to tackle the illegibility issue.
I still get comment spam occasionally though - I haven't yet figured out if the spammers' robots are able to read the CAPTCHA much better than us mere humans, or if it's actually humans posting the comment spam. Now if they could only come up with something which genuine readers find easy to solve but spammers can't get round.... but of course that's the Holy Grail of captcha.
