Right, but how do you know what language the viewer is using? Just
because your page is in English doesn't mean I'm a native English user.
In other words, a language-specific validation methods is going to add
more cognitive load with no additional security benefit. An ideal
solution should be language-agnostic, which is what the current audio
and image captcha does.
It's a tough nut to crack. We want something only a human can solve
which doesn't presume a certain language proficiency and is accessible.
Non-trivial at best.

One other tidbit. The numeric puzzle solving example you give would
have a lot of internationalization issues. You would need localized
translations of every question, which is probably not going to
happen. The web is not just in English.
