Is Peter Coffin in French a Coffin?

There are 899 minions in the film. The language sounds so difficult to do. Every word is, I think, a real word from one language or another. There's some gibberish as well. Who also does some minion voices? Jermaine Clement from Flight of the Comcords does one. And then this guy, and someone else, but this guy does 899 minions.
