The reasoning given by Alex Amancio as to why they all don't have French accents is that everyone Arno comes into contact with speaks French. There are no foreign accents, so the Animus has no trouble translating the accents. That it would have trouble translating an Arabic word to English isn't beyond me.

I don't understand why this is such an issue. Obviously they've thrown the reference in as fanservice, but from an in-universe standpoint it's not contradicting anything.
