Any API to dub videos into multiple languages?

We're producing lcalized video content across different markets and the workflow is a nightmare right now. Basically we need something that can take a finished video, swap the voiceover into 4 or 5 languages and ideally keep the background audio intact underneath. The bigger issue is scale, we can't do this one by one manually for every single asset. What I'm really trying to find is an API that handles video dubbing at scale, something we can pipe into our existing pipeline without rebuilding everything from scratch. We already use a tool for AI-generated soundtracks that syncs music to the video's emotional pacing automatically, which honestly saves us maybe 40+ hours a month on audio production alone, so I know the API ecosystem for video audio tools is maturing. Anyone know if a dedicated dubbing API exists that handles lip sync, voice cloning or at least clean audio replacement across languages? Even a rough cost ballpark would help us figure out if its viable.
