This morning some cryptic information was posted to the Square Enix Facebook page this morning regarding what appears to be an upcoming RPG for the iPhone. The only details provided with the screenshot are as follows:

According to the info that I've got,various characters can be generated from your "voice". Please wait for the official announce for the detail. I'll keep you updated.

This isn't the first time Square Enix has utilized sounds to generate characters in a game, as the entire gimmick behind Song Summoner was using your music to generate allies to assist you in battle. We should know more soon, as I doubt they'd release this information without more details in the pipe. We'll follow up as soon as we hear more.
