This is called the "dub," and it usually requires voice artists to record the lines in this new language
in a way that matches the original tone of the show or movie. This requires time and money, something studios aren't always willing to part with.
The article discusses the author's experience with Prime Video's new AI dubbing feature, which aims to provide real-time dubbing in multiple languages. The author tested this feature on the show "Gen V," a spin-off of "The Boys," focusing on how the AI handles dialogue, accents, and emotional nuances. While the AI dubbing managed to keep up with the fast-paced dialogue and maintain some level of emotional expression, it struggled with naturalness, often sounding robotic or off-sync. The author notes that while the technology shows promise for breaking down language barriers in media consumption, it still has significant room for improvement in terms of voice modulation, lip-sync accuracy, and the natural flow of conversation. The overall impression is that AI dubbing is an innovative step forward but currently falls short of replacing human dubbing in terms of quality and authenticity.
