What’s unclear at this point is what else beyond the figure itself will be added. Since 1993, the sitting President hasn’t only given his likeness to the Hall of Presidents, but his voice as well. The current President has spoken to the audience through the animatronic, giving the oath of office or giving a speech. One would assume that the Biden animatronic will do the same, though Disney World has yet to actually confirm that. It may be that arrangements to do the recording simply have not been made yet and no announcement will be made until that has been done. If Biden was, for some reason, unwilling or unable to do a recording, Disney likely wouldn’t want to announce plans to have Biden speak and then have to go back on that.
