I downloaded an app call Jeanie for android. You can name her FI and she will call you master. Its free and its a voice recognition app like Apple's Siri. You can name her whatever and name yourself whatever. But, i thought I would share that for all the Skyward Sword fans. Hey you can put Navi also. Wow I'm a nerd.
