I have also heard Naushika (pronounced now-SHH-eka) and I was wondering where does that pronunciation come from and is it technically correct to underplay or even omit the sound the "i" makes? I've been led to believe it's Russian in origin but I don't know.
The "Naushika" pronunciation may come from the Japanese form, ナウシカ (Romaji: Naushika). "Si" and "shi" are the same in Japanese.It's spelled Навсикая (Navsikaya) in Russian.
In English, it is most commonly pronounced NAH-si-kə.

In English, Nausicaa can be pronounced either now-SI-kee-uh, or now-si-KAY-uh. If spelled Nausicaä, then the second pronunciation is the only one.In modern Greek, however, it is pronounced nahf-si-KAH.

In my literature classes, I've heard this pronounced a few different ways. Naw-sih-KAY-ah, naw-SHEE-kah, and now-see-KAY-eh. I'm not sure which is correct.
