Thanks a lot.

What do you mean change the country?
I change the country in alexa app or amazon account website?

Would i be able to control alexa in french for kodi?
What about my others skills in french?

Content country in your Amazon account (on amazon website). You will have to provide some "fake" address in either of those countries. (This is how I have it set up)

This is a smart video alexa skill, and doesn't follow the same rules as your other skills. It will be available in french once Amazon makes it available in it.
