Difference Between Voice-over and Dubbing

Key Difference

Voice-over and dubbing are both techniques used in audio and video productions to replace or supplement spoken dialogue, but they serve different purposes and are executed differently. Voice-over involves a narrator or commentator speaking over the original audio track, often used in documentaries, news reports, and instructional videos.

The original audio is usually still audible beneath the voice-over. Dubbing, on the other hand, is the process of replacing the original dialogue in a film or television show with dialogue in another language. It involves careful synchronization of the new audio with the actors’ lip movements and expressions to maintain the original performance’s authenticity.
