Personally - I use SwiftKey with two languages enabled. Its really good at predicting the language I will use based on the first word.

Bit more tricky when you mix english terms into a different language but still pretty damn impressive.

SwiftKey works wonders for me also, it's great with french with all the j' and l' and prepends those contractions correctly in front of the word I'm trying to type (swipe?). Definitely recommended, even better since it's free now.
