Part 1: What is Dubbing?

Dubbing refers to the post-production process used in film and video production to synchronize sound design. It involves adding new dialogue and other sounds to the existing tracks of a project that has already been filmed.

In the film industry, "dubbing" typically refers to the practice of replacing the voices of actors with those of different performers speaking another language. This is commonly known as "revoicing" in the film industry.

Part 2: The History of Dubbing

In the early days, due to limitations in film sound, dubbing emerged. In 1923, inventor Lee de Forest introduced the first viable optical film sound technology - the Phonofilm. Later, Bell Labs and its subsidiary Western Electric developed a 16-inch wax disc spinning at 33.3 RPM, capable of recording 9 minutes of sound, with better sound quality than Phonofilm. Warner Bros. decided to collaborate with this industrial giant.

The machine, called Vitaphone, had a signal-to-noise ratio significantly better than the consumer standard 78 RPM. Vitaphone made its debut in a packed auditorium in New York and San Francisco in 1925, playing a recorded speech by President Harding.

Since then, people have been looking for ways to integrate sound into film. It wasn't until 1926 that Warner Bros. obtained exclusive rights to the Vitaphone sound disc system and later that year released their first sound film, "Don Juan." George Groves used Vitaphone to record the music played in the film, becoming the first music mixer in film history to do so.

Part 3: What is Dubbing Purpose?

Film Dubbing

Dubbing is commonly used to translate foreign films into languages desired by the audience. The translated dialogue from foreign films is dubbed into the same video, allowing audiences of different languages to watch. Dubbing actors need to decide what words to use for dubbing based on context, tone, gestures, and the script.

Music Dubbing

Music dubbing typically involves integrating written lyrics into a song after the creator has established the melody and tone of the entire song. Lyrics are sung in a recording studio while instrumental accompaniment is played. Finally, the melody and dubbing are merged together.

Video Game Voiceover

There is currently a wide variety of popular video games, available on both computer and mobile platforms, including competitive and puzzle games. Video creators add voiceovers to their videos either during or after recording.

Video Voiceover

Short videos are likely to have been watched by many people, and the content is particularly rich. When creating videos, video creators usually write scripts before shooting the video. After shooting, the content is voiced differently. For example, documentaries have some explanatory narration, movie reviews have commentary, and vlogs have inner thoughts of characters, and so on.

Part 4: Different Types of Dubbing


Voiceover typically tends to be narrative in nature and is often not synchronized with the actions of the characters in the video. The purpose of voiceover is to convey overall information.


Looping, also known as ADR (Automated Dialogue Replacement) looping, is commonly used in feature films. However, this method is expensive, difficult, and time-consuming. Essentially, it involves the process of repeatedly narrating short phrases until they are perfectly synchronized.


Voice-over narration involves lowering the volume of the original audio while raising the volume of the voiceover recording. This technique is often used in reporting international news. Synchronous recording ensures that it matches the duration of the original audio.

Lock-to-Picture Recording

This is an alternative approach to ADR that is cheaper but involves a different process. Professional voice actors watch the video footage while recording voiceovers to mimic the original performance.
