Amazon Prime Video rolls out AI lip-sync dubbing for foreign-language content
The streaming service is using artificial intelligence to synchronize actors' mouth movements with dubbed audio in different languages, starting with the German series Maxton Hall.
The Verge
Amazon Prime Video is deploying a new artificial intelligence system designed to realign an actor's mouth movements with translated voice recordings. The technology currently powers the English version of the German drama Maxton Hall, though the company has signaled plans to bring it to more titles down the line.
How the technology works#
Prime Video's approach combines AI algorithms with visual effects techniques to automatically adjust lip movements so they align with dubbed dialogue. The company has confirmed that human voice actors perform the dubbed audio—the software then handles the visual synchronization rather than replacing human performers.
This approach builds on earlier developments in the streaming and creator spaces. Meta and YouTube have each rolled out their own AI dubbing options in recent months, some of which include optional lip-sync adjustment to enhance the illusion of native-language speech.
Expansion of previous dubbing experiments#
Prime Video's move follows a pilot program launched last year where the company tested AI-assisted dubbing across a dozen films and television shows, working in English and Spanish with titles including El Cid: La Leyenda, Mi Mamá Lora, and Long Lost.
The lip-sync dubbing feature is now accessible globally for the first two seasons of Maxton Hall. Viewers will gain access to the technology when the show's third season premieres on December 9th.
