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. At 17 credits per second, it is the premium-tier talking head model — a 10-second clip costs 170 credits. The newer OmniHuman v1.5 (19 credits/second) 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 more affordable Kling LipSync (17 credits/job flat) or budget Pixverse (6 credits/second).
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 at a lower price point. At 17 credits per job (fixed, regardless of audio length), it sits in the middle tier between OmniHuman's premium pricing and Pixverse's budget rate of 6 credits/second. 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 and cost champion for talking head videos — priced at 6 credits per second of output, it makes high-volume production affordable at any scale. A 10-second clip costs just 60 credits compared to Kling LipSync's fixed 17 credits (cheaper only for very short clips) and OmniHuman's premium pricing. 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 makes the math work.
