> I think the sound is Z in all of them? It's partly a question of whether the orthography of the language uses S for a Z sound or not. I'm confused here. What you call "the Z sound" in "synthetisieren" or "synthétiser" does not sound the same as "the Z sound" in "sintetizzare", for instance. The letters Z and S both exist in those languages, but they pronounced differently.
