Introducing ByteDance Avatar Omni Human on WaveSpeedAI

ByteDance OmniHuman Is Now Available on WaveSpeedAI: Transform Any Portrait Into a Lifelike Talking Avatar

The future of digital human creation has arrived. We’re thrilled to announce that ByteDance’s groundbreaking OmniHuman is now available on WaveSpeedAI, bringing you the most advanced portrait-to-avatar technology ever developed. With just a single image and an audio clip, you can now create stunningly realistic videos featuring lifelike motion, expressive gestures, and perfectly synchronized lip movements.

What Is OmniHuman?

OmniHuman is ByteDance’s revolutionary end-to-end AI framework designed to generate highly realistic human videos from minimal input. Unlike traditional approaches that require extensive video footage or complex motion capture setups, OmniHuman transforms a single portrait photograph into a dynamic, speaking avatar that moves naturally and expresses genuine emotion.

Developed by the same team behind TikTok’s cutting-edge AI technologies, OmniHuman represents a significant leap forward in human video synthesis. The model was trained on an extensive dataset of over 18,700 hours of human video footage, enabling it to understand and replicate a remarkable range of motions, expressions, and subtle human behaviors.

What sets OmniHuman apart is its multimodal conditioning approach. Rather than relying on single signals like audio or pose data alone, OmniHuman integrates multiple condition signals during training—audio, video, and pose references—creating what the researchers call “omni-conditions training.” This unified approach results in dramatically more realistic and coherent output.

Key Features

Industry-Leading Lip Synchronization OmniHuman achieves exceptional precision in lip-sync accuracy, with benchmark results showing a lip sync error of just 1.2mm compared to the 2.8mm industry average. Phoneme accuracy reaches 94%, significantly outperforming the 78% achieved by leading alternatives. Whether your subject is speaking, singing, or performing, the lip movements match the audio with uncanny precision.

Full-Body Animation Support Unlike competitors that focus primarily on facial or upper-body animations, OmniHuman generates complete full-body animations with lifelike gestures, natural gait, and synchronized movements. From portrait shots to full-body compositions, the model adapts seamlessly to any aspect ratio and body proportion.

Expressive Facial Animation The model captures the subtle nuances of human expression—micro-expressions, emotional transitions, and natural facial dynamics that make the difference between artificial-looking output and truly believable video content.

Versatile Input Support OmniHuman works with real human portraits, animated characters, cartoon illustrations, and even stylized artistic images. This flexibility opens up creative possibilities across diverse content styles and applications.

Audio-Driven Generation Provide any audio clip—speech, singing, or narration—and OmniHuman will generate corresponding video with accurate lip movements, appropriate gestures, and natural body language that matches the tone and rhythm of the audio.
