LatentSync AI reshapes the speaker's lip and jaw region frame-by-frame to perfectly match the new dubbed audio.
Spimov's AI lip sync reshapes a speaker's mouth and jaw region frame by frame so their lips match the new dubbed audio — not the original language. Using LatentSync technology, it analyses the video and regenerates the lower face to align with each translated word, making dubbed videos look natural rather than obviously overdubbed. It works on real footage of real people, across 600+ languages, and preserves the rest of the frame untouched. This is the difference between a dub viewers notice and one they don't: proper lip sync keeps audiences immersed and improves watch time on localized content. Creators use it for YouTube and courses, brands for ads and training. Lip sync runs as part of Spimov's dubbing pipeline on paid plans, on top of transcription, translation, voice cloning and mixing.
