Square Enix could be working on a project called Voice Fantasy.
How do we know? They filed a trademark for Voice Fantasy in Europe. While this sounds like it could be the name of a new Final Fantasy vocal CD, the mark isn’t applicable to music. The Voice Fantasy filing is only good for computer games, video game software, and strategy guides.
What does this sound like to us? Voice activated Final Fantasy (“fight!”, “summon!”, “mega flare!”) or perhaps a Song Summoner style game where spoken words create units.
