Create natural-looking talking head videos by syncing audio to a portrait. Choose a lipsync model below for workflow-specific guidance.
ByteDance
OmniHuman by ByteDance produces the most realistic talking head videos of any AI model on Martini. Given a single portrait photo and an audio track, it generates video with natural lip sync, subtle facial micro-expressions (eyebrow raises, eye squints, jaw tension), and organic head movement that makes the result nearly indistinguishable from recorded video. It sits at the premium tier of talking head models. The newer OmniHuman v1.5 offers further refinements. Both output at 720p in three aspect ratios (1:1, 16:9, 9:16). If realism is your priority — for executive presentations, keynote addresses, flagship marketing, or professional courses — OmniHuman is the clear choice over the lighter Kling LipSync or the high-volume Pixverse Lipsync.
Kling
Kling LipSync brings Kling's industry-leading human motion engine to audio-driven talking head generation, producing smooth, natural lip movements and facial expressions that rival OmniHuman with a lighter render. It charges per job rather than per second of audio, so render time stays predictable regardless of clip length — placing it in the middle tier between OmniHuman's premium quality and Pixverse Lipsync's per-second high-volume model. The architecture advantage: Kling LipSync is powered by the same engine that makes Kling 3.0 the best video model for human motion, meaning jaw movement, cheek deformation, and chin motion are anatomically accurate rather than approximated.
Lipsync
Pixverse Lipsync is the speed champion for talking head videos — billed per second of output, it makes high-volume production fast at any scale. For very short clips, Pixverse can finish faster than Kling LipSync's per-job model; for longer clips, Kling becomes the more efficient choice. The quality trade-off is real: Pixverse produces lip movements that look "good enough" for social media and web content, but lack the anatomical precision of Kling or the ultra-realism of OmniHuman. If you need 10+ talking head clips for a content series, educational course, or multi-language localization, Pixverse is the only model that scales without compounding render time per clip.
