AI lip sync takes a portrait and an audio track, then renders a video where the mouth, jaw, and micro-expressions match the speech. Upload a photo, drop in audio or text, get a talking-head clip in under a minute. Try lip sync free below.
The model that turns a still portrait into a talking-head video
Lip sync is a workflow where a neural model takes a portrait (still or video) plus an audio track and outputs a video where the face appears to speak the words. The model maps phonemes to mouth shapes, blends jaw movement, eye blinks, and subtle head motion, and preserves the rest of the frame. A modern lip sync render finishes in 30 to 90 seconds. Common use cases: explainer videos, audiobook covers, multilingual dubs, talking avatars, and rapid product demos. Lip sync replaces the long path of teleprompters, full reshoots, and frame-by-frame rotoscope.
Upload a portrait and an audio track. A lip sync model handles the mouth shapes, jaw, and blinks β no animator.
Don't have audio? Type the script and pick a voice. Lip sync drives the face from the synthesized track β no recording needed for a lip sync clip.
A lip sync render can drive the same face in English, Spanish, Japanese β useful for multi-market campaigns.
A good lip sync render preserves identity β same face, same wardrobe, same lighting. Only the mouth and jaw move.
16:9 for YouTube, 9:16 for Reels, 1:1 for feeds. Set it before rendering β lip sync respects the framing.
A lip sync clip renders in 30-90 seconds on current models. Iterate freely on each lip sync take instead of committing to one reroll.
Lip sync β portrait in, audio in, talking video out, no editing bench in between.
You upload the portrait and the audio (or type a script); a lip sync model maps phonemes to mouth shapes, blends jaw motion, and preserves the rest of the frame. Explainer hooks, audiobook covers, podcast clips, multilingual ads β output specificity tracks the audio quality and the source portrait.
Lip sync pairs naturally with TTS β pick a voice, type lines, drive the face.
Don't have a clean audio recording? Type the script, pick a voice from the catalog, and the lip sync render drives the face from the synthesized track. Useful for explainer hooks, demo voiceovers, and quick variant tests where re-recording would be a blocker.
A lip sync model can drive the same portrait across English, Spanish, Japanese, and more.
Localizing a campaign used to mean re-shoots in every market. Lip sync renders a separate video per language from the same portrait, so the spokesperson stays the same and the mouth shapes match each language. Useful for global ads, multi-market explainer content, and personalized outreach.
Lip sync animates the mouth and jaw β the rest of the face, hair, and wardrobe stay locked.
Old talking-head animation tools recolored skin or warped features as the model added motion. Modern lip sync respects identity: the face stays recognizable across the clip, lighting carries, wardrobe doesn't drift. Useful for branded talent, founder cameos, and any portrait where the person needs to stay on-model.
Speed matters β you iterate when each take costs 30 seconds, not 30 minutes.
Old talking-head pipelines required a teleprompter, a recording session, and a designer pass. A lip sync render returns in 30-90 seconds, which means ten variations in 15 minutes β pick the best, refine, move on. Iteration speed is the real workflow change.
Eight clips β each caption is a reusable lip sync brief
When AI lip sync beats a reshoot or rotoscope β and when it doesn't.
| Workflow | Lip sync AI | Manual rotoscope | Recorded talking head |
|---|---|---|---|
| Time to first clip | 30-90 seconds | Hours to days | Hours to days |
| Source needed | One photo + audio | One photo + animator | Talent + studio |
| Multilingual variants | Rerun with new audio | Re-rotoscope each line | Re-shoot per language |
| Identity preservation | High β face locked | High but labor-intensive | Original talent |
| Skill barrier | Upload + audio | Animator + comp skills | Director + crew |
| Best at | Quick variants and dubs | Bespoke art direction | Live performance |
Four habits that separate usable footage from reroll noise
Front-facing photo, mouth closed or neutral, clear lighting. A good source gives the lip sync model more to anchor on and less to invent.
Studio recording, denoised TTS, or a clear voice memo. Lip sync output tracks audio quality β a lip sync render on noisy input gives muddy mouth shapes.
16:9 for YouTube, 9:16 for Reels, 1:1 for feeds. Most lip sync renders sit at 5-30 seconds β long enough for a hook or one-liner.
Each lip sync pass is under 90 seconds. Run two or three with slightly different audio takes, compare, keep the best.
Each category has its own strengths β animation style, motion source, audio support
