My guesses while speculating after patch 4.4 were all time-travel based, since the Voice's words are mostly taken from (if I remember correctly) a time-travel spell in Tactics.

So my thoughts at the time were: future Alphinaud, future Unukalhai, or (since I'd read a rumour/leak claiming the Crystal Tower was going to be involved in 5.0) future G'raha Tia.

And now we have the 5.0 poster, featuring a mysterious hooded figure who (I and some others think) looks an awful lot like G'raha.

Regardless of whether that resemblance is intended, or it's supposed to be a new character entirely, it would be a reasonable possibility that the person on the poster might be behind the mysterious voice.
