I will point you at http://www.cepstral.com/ for a possible
solution to your
.mp3 usage. You could use Cepstral's "swift" tool to say the text
dynamically.
Actually Ted, what I was referring to was that you could say actual "words"
like "rainbow6", or even made up strings such as "A35SFX". Much like a text
captcha does. As it stands, I think most audio captchas use simply digits,
which means you only need to understand [0-9] in your voice-breaker-code
(http://vorm.net/captchas). Mixing in letters means another 26 variants, and
if you went with words (which 'swift' will 'speak'), then you're in another
stratosphere all together...
D. Vin:
That's an interesting idea. As I said in my last post on this subject
sound files can convey different meanings than just recognizing that
the word "seven" means providing 7 as a solution.
However, we run into the problem of those with cognitive disabilities
who may not be able to resolve the CAPTCHA solution.
As I see it, this is a double edged sword. If a blog, for example,
requires cognitive skills to derive benefit from, is it unreasonable
to present a cognitive problem for the user to solve?
Let's take an extreme example -- What if you had a blog that
discussed color arrangements, would be be acceptable for the blog
owner to put up a color-blind CAPTCHA?
Interesting topics for discussion, but probable not for this list.
Thanks everyone.
Cheers,
tedd
