What is Language Dubbing?

Language dubbing is a post-production process used in multimedia, where original dialogue of video content is replaced by voiceovers in a different language. The new audio, called dubbed audio, is created by voice actors who reenact the original audio, synchronizing their voice with the mouth movements of on-screen characters.

The Difference between Dubbing and Subtitles

Dubbing and subtitles are two primary methods of making content accessible to foreign language audiences. While dubbing replaces the original dialogue with a new audio track in the target language, subtitles provide written translations of the original language at the bottom of the screen.

For example, an English dub of a popular Spanish series like "Money Heist" would involve voice actors replacing the original Spanish dialogue with English. Alternatively, subtitles would display English translations while the original Spanish audio plays.

Why Do They Call It Dubbing?

The term "dubbing" originated from the process of "doubling" the original voice track with a second voice track in a different language. Over time, this term shortened to 'dub', and the practice became known as 'dubbing.'

The Use of Language Dubbing

Language dubbing serves to localize foreign language content, making it more accessible and enjoyable for audiences who speak a different language. It enables the original dialogue to be conveyed in the viewer's own language, removing the language barrier.

Why Do They Need to Dub Movies?

Dubbing is crucial in the film industry, especially for Hollywood and other global cinema industries. It broadens the market for movies, making them understandable to audiences who don't speak the film's original language. For instance, Hollywood movies are often dubbed into Hindi, Portuguese, Spanish, and many other languages for distribution in different countries.

Advantages of Dubbing

Dubbing has several advantages. It offers viewers the opportunity to enjoy video content in their native language without needing to read subtitles. This is particularly helpful for complex or fast-paced films where reading subtitles can detract from the viewing experience. Furthermore, dubbing can help retain cultural nuances by allowing for adaptations in the dialogue that subtitles might not capture.

Watching Movies with Subtitles

While dubbed videos provide audio in the viewer's language, subtitles offer an alternative method of understanding foreign language content. Subtitles can help viewers learn a new language, improve listening skills, or enjoy a movie in its original language while still understanding the dialogue. For instance, many English-speaking Netflix users watched the Korean series "Squid Game" with English subtitles.

Languages Often Dubbed

English, Spanish, Portuguese, and Hindi are among the languages that are often dubbed. For instance, popular shows in Spain or Latin America are frequently dubbed into English for a broader audience. Similarly, Hindi dubs are common for Hollywood movies shown in India.
