Article: There is very little voice acting in the game, as is the case in most Zelda titles to date. Link remains silent in conversation, but grunts when attacking or injured and gasps when surprised. His emotions and responses are largely indicated visually by nods and facial expressions. Other characters have similar language-independent verbalizations, including laughter, surprised or fearful exclamations, and screams. The character of Midna has the most voice acting—her on-screen dialog is often accompanied by a babble of pseudo-speech, which was produced by scrambling the phonemes of English phrases[better source needed] sampled by Japanese voice actress Akiko Kōmoto.
