All:
Does anyone have examples of CAPTTCHA with audio alternatives that are
multi lingual? Pronunciation of alphanumerics is not the same in all
languages, so if someone selects Japanese and gets Japanese text, are
there any audio alternatives that include such various languages in the
synthetic speech used?
Thanks in advance.

Hi Allen.
I've not seen anything like that, but I do want to make one small correction. Most captchas do not use synthetic speech. The few that do, in my experience, tend to be extremely difficult to solve. Most good audio captchas use real human speech, and so are usually a little easier to understand.
That being said, I would encourage you or anyone who is contemplating using captcha to consider all of the alternatives first. Captchas should be the absolute last option, and even then they should be avoided.
Good luck.
Aaron

Hi Alan,
Like Aaron, I haven't come across any multi-lingual CAPTCHA audio.
I'd also like to second Aaron's call to avoid CAPTCHA wherever possible.
Server solutions need to be found if the web is ever to become broadly
accessible.
Imagine the isolation of someone who is deaf-blind ... And how
frustrated they will be to find that they need either sight or hearing
to be classed as human. Text or exception CAPTCHA should really be the
alternative if an image challenge is used. The first asks simple
questions and the second requires that a field is left blank. Neither
is foolproof, but then the same can be said of image CAPTCHA now.
Cheers,
Bim

Do you mean audio CAPTCHAs that our "localized" according to the
language of the rest of the page or do you really mean audio CAPTCHAs
that contain speech in more than one language?
I did a quick search for audio CAPTCHAs in French, German and Dutch.
eBay France uses a visual CAPTCHA and an audio CAPTCHA in French. Since
the rest of the registration page is only available in French, I see no
reason to provide the audio in languages other than French. (I didn't
see a CAPTCHA on the registration page of the German eBay site or
on the two versions (French and Dutch) of the Belgian eBay site, nor
on the Dutch eBay.nl. I also checked Yahoo France and Yahoo Deutschland;
they use purely visual CAPTCHAs.)
Best regards,
Christophe

I am looking for a CAPTCHA that would produce audio with the language
specified in the previously selected choice of language. For example,
front page has language selection, and then brings up CAPTCHA, with
audio alternative. When audio CAPTCHA alternate is selected, it would
use pronunciation rules for that selected language.
