AI Lip Sync Generator
Sync any voice to any face. Upload a photo or generate a character, add audio or a script, and Hedra's speech-native models produce a lip-synced video — mouth shapes, timing, and expression driven by the audio itself.
How to Lip Sync a Video with AI
No camera, no keyframing. Three steps from a still image to a speaking video.
Upload a Face or Character

Use a photo of a real person, a brand mascot, or generate a character from a description — any face the video should speak through.
Add the Audio

Upload a recording, record directly, or type a script and pick from 4,000+ AI voices in dozens of languages. The audio drives the performance.
Generate
Hedra syncs mouth shapes, timing, and expression to the audio and renders the video — ready to download or keep editing in the studio.
Why Lip Sync with Hedra
Lip sync is Hedra's home turf — the research behind Character-3 started here.
Built for Speech, Not Just Motion
General video models animate; Hedra's character models perform. Mouth shapes track phonemes, and expression follows the emotion in the audio.
Any Voice, Any Language
Upload your own recording, clone a voice, or pick from 4,000+ AI voices. The same character can deliver the same script in multiple languages.
In the Studio or Through the API
Make one video in the browser, or generate lip-synced video programmatically on Hedra's developer platform.

What Creators Lip Sync
Anywhere a face needs to speak, lip sync is the shortcut past the camera.
UGC and Creator Content
Ship talking-head content daily without filming daily. One character, endless scripts, consistent delivery.
Explainers and Ads
Put a spokesperson in front of every product without a shoot. Swap the script, keep the face, test more creative.
Training and Onboarding
Turn documentation into a presenter-led video, and re-generate it when the content changes instead of re-filming.
Localized Versions
Generate the same character delivering the same message in different languages — lip sync matches each language's audio, not a dubbed overlay.

Frequently Asked Questions About AI Lip Sync
Everything you need to know before you generate.
Hedra's character models are audio-driven: they read the speech itself and generate matching mouth shapes, head motion, and expression frame by frame. You provide a face and the audio; the model produces the performance.
Yes — upload a recording or record directly in the studio. You can also type a script and use one of 4,000+ AI voices, or clone a voice with AI voice cloning.
Yes. Lip sync follows the audio, so any language the voice speaks, the character speaks — with mouth shapes matched to that language, not an English overlay.
Lip sync is the technology; a talking avatar is what you build with it. If you want the full workflow — characters, scripts, voices, and video in one place — see Hedra's AI talking avatar page, or start from a single photo with talking photo AI.
Yes to start — the free plan includes 100 credits, enough to make your first videos. Paid plans add more credits and full commercial rights.
