They don't do a voice-over in either French or Spanish, if that's what you mean. They however add French/Spanish/German/Italian subtitles (I think there are a couple more, actually, but both FF X and FF X-2 were at least subtitled in those languages, if I remember well), as well as translate all the menus, items and ability names (usually for really dumb-sounding ones, i.e. FF IX in French....)
French Mag Gameplay RPG has also confirmed an early 2007 release date for Europe in its July issue. So glad I've got the japanese game already, even if I'll get the European version for the dialogs - my Japanese isn't that good, unfortunately....
