I think in most Austrian resorts you won't have a problem, lots of ski schools have classes conducted in English. Hotels, restaurants shops will have at least one employee who speaks English. I can't speak for France as I have only skied there as an experienced skier so didn't need lessons and I can speak and understand some French but I think at most major resorts you shouldn't have many problems.

English speaking instructors in all major resorts in France as well as hotel/bar staff
