What is it that her nationality is being based on? Her voice? It shouldn't be; no definite nationality can be assumed from her voice alone, seeing as it is different in all four games. Her name is the only other thing that we can guess her nationality from and even if a specific one was agreed on by all of us, it would still be assumed, not backed up by any official sources and thus, speculation.

Since her nationality is never stated in any official media I would be in favor of simply removing that part from the sentence.
