In filmmaking, dubbing or looping is the process of recording or replacing voices for a motion picture. The term is most commonly used in reference to voices recorded that do not belong to the original actors and speak in a different language than the actor is speaking. "Dubbing" can also be used to describe the process of re-recording lines by the actor who originally spoke them. This process is technically known as automated dialogue replacement, or ADR.

Although dubbing is most common with film, television series are sometimes dubbed as well (mostly popular Hollywood series and serialized Japanese anime that have received foreign distribution). Foreign-language films and videos are often dubbed into the local language of their target markets to increase their popularity with the local audience by making them more accessible.
