AI Lip Sync
You have a portrait or a video of a spokesperson and a recorded voiceover, and the mouth needs to match. Astorie chains an audio node into a lip-sync video node so your character speaks the line cleanly — same identity, accurate phonemes, frame-aligned. Works for spokespersons, dubs, and dialogue scenes.
What this feature solves
Spokesperson video used to mean booking talent, a studio, lights, audio, and a half-day shoot for thirty seconds of dialogue. AI lip sync collapses that to a portrait, a script, and a voice take — but only if the sync is good. Bad lip sync is uncanny and unusable: the mouth lags, the phonemes are wrong, the head moves like a doll. Brands cannot ship that.
Stand-alone lip-sync tools force a brutal handoff. You generate the voiceover in one tool, the portrait in another, and try to bolt them together in a third — losing identity along the way and ending up with mouth shapes that fight the audio. There is no canvas where voice, video, and sync live together as one chain, which means every revision is a multi-tool re-do.
The deeper need is multi-language dubbing and dialogue at scale. International campaigns, course content, and explainer video all require the same spokesperson speaking different scripts and languages. Without a workflow that holds the character identity while changing the audio, every language becomes a new generation, a new approval cycle, and a new chance for the talent to look slightly off.
