Dubbing

From Conservapedia

Dubbing is the process of adding voices to an audio track. It is commonly used in the film and television industries to make the characters speak English in a foreign film. This can be done as an alternative to subtitles, since many viewers find reading text to be more distracting than the dissonance of a voice not matching the movement of a person's lips.

Dubbing is usually serious, though it can have intended or unintended comic effects, such as in Hong Kong action movies (cf. Jackie Chan). Dubbing can also be used for parody, replacing the actual spoken words with other ones.
