Amazon Prime Video is testing a new artificial intelligence feature that synchronises dubbed audio with the original video footage. The system is currently limited to the English dub of the German series Maxton Hall, but the company plans to roll it out to more titles in the future.

The tool is designed to align an actor's mouth movements with the new dubbed audio track. This approach differs from fully automated dubbing, which often struggles to match lip movements accurately. By using human-dubbed audio as a reference, the system aims to reduce the uncanny effect that can occur with purely synthetic voiceovers.
