Kinect voice recognicion does not support most of Europe yet. It is supposed to add German, French, European Spanish, etc. (I think 7 other langaues) with an update this spring.
It looks like France will get French support for Kinect in April:

I sort of suprized they didn't wait to launch it till they had the langague support.
