Multilingual audio files?

cm0n commented 8 years ago

Hello,

is there any example of multilingual audio files, can be so chosen between different languages? All I found was only for text.

Hi Philip! Thanks for considering visualCaptcha!

There's no example, as the implementation can vary considerably depending on your needs. In any case, I suppose you can add a URL like audios.php?lang=en and return a JSON response depending on the chosen language.

Does that make sense? Thanks.

Unfortunately I do not know how to do it in other Captcha system, but I would have rather thought that generated the audio files. Yes is possible to add this to url as flag, but how I get the Audio Files for a lot of languages? I need a system which is flexible in the use of language.

In addition, I believe that still a problem in the field of accessibility.

The contrast in high-contrast mode is very bad, see picture. The contrast must always be at least 3:1 be to come as well.

Putting the tabindex on the image's contrast quite bad, he must be on the a element. In addition, then the a element is missing an alt text with empty href.
These are just points that I discovered quickly that, since I am working on a software that needs to be almost 100% disability access. I think is hard to implement accessibility captcha system, that not easy to solve by a robot.

I hope you understand my points.

@cm0n Thank you for those details!

As for "generating" the audio files, I don't remember what I used, but something like http://www.fromtexttospeech.com/

As for the contrast, I wasn't aware of that, you can, however reverse the images or make them white via CSS (or just update the images).

I'm happy to take in a PR with these updates or guide you towards where to make them, if that makes sense!
