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.)
