You know, Auto-Tune is supposed to be used to correct flaws in your pitch and such. People from Britney Spears to Tim McGraw or Faith Hill have used Auto-Tune, and have you ever heard them on some T-Pain or Lil' Wayne type Auto-Tune shit? That's what makes Auto-Tune and Talk Box different. Auto-Tune is something designed to fix errors for singers and someone just pushed it to another level to create a completely different sound with it, while the Talkbox was designed to actually change the sound of instruments and/or your voice to give it a different sound.
