Square Enix's latest iPhone/iPad/iPod Touch game is "Voice Fantasy," an RPG-like battle game where you summon characters using voices.

The game appears to be entirely battle based. The battles take place automatically. In "Single Match" mode, you place two characters against one another. "Tag Match" mode is for two on two fights. In "Demon King" mode, your characters face off against monsters.

You summon characters by having the game read in audio files of you and your friends speaking. The game creates characters with differing jobs, abilities and personalities based off the voice properties.
