If you are referring to "other language versions" of M2TW, I think so. At any rate, this has not (yet) been a problem within the EB team (where there would be some variety between languages, Steam/no-Steam versions of the game). Of course, for the sounds to be translated into German, you need someone to record equivalents in German instead.

If you want this tool to be translated into German itself, then someone needs to volunteer and we can integrate German (or pretty much any language) quite easily. In fact, it is covered as part of the readme.
