How to pronounce Fëa?

Would it be pronounced Fay-uh or Fee-uh or something else?

Fë-a [FEH-ah] IPA: 'fɛ.ɑ

In The Lord of the Rings Tolkien would often put a dieresis (¨) on one of the vowels to indicate each vowel was pronounced separately: ëar. Thus Quenya ear “sea” is pronounced as disyllabic “EH-ahr”

Thanks!
