Run Lip Sync Models with Accelerated Inference
Hedra is a visual intelligence and inference company. Run third-party audio-driven models — including Kling AI Avatar, OmniHuman, and VEED Fabric — in Studio or through one API, with accelerated compute behind every generation.
How to Run a Lip Sync Model
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 Run Lip Sync Models on Hedra
Hedra provides accelerated inference for leading visual models, including audio-driven models from other companies. Lip sync is a capability of the selected model — not Hedra's product category.
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
Run selected third-party audio-driven models in the browser or through Hedra's developer API, backed by accelerated inference.

What Creators Make with Lip Sync Models
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.
