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

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

Subject: [WebAIM] multi-lingual CAPTTCHA

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.
