Aside from the visuals, the game's audio attracted comments. GameSpots staff enjoyed listening to the story unfold through the recorded voices. They found that the voice actors did not overact their roles despite the extravagant appearances of the characters. Instead, the actors' performance conveyed an extra depth to the personalities of these characters. Haumersen noted a few flaws in the game's vocal presentation: the character models' lip movements did not match their speech, and they had a limited number of gestures to accompany the words. Michael L. House of AllGame was not altogether impressed, finding the voice acting to be "spotty[,] ... ranging from hilarious to obnoxious."
