OmniHuman 1.5 API Features
Audio Semantics-Driven Expressive Motion
OmniHuman 1.5 excels in interpreting speech content, timing, and prosody to generate natural gestures, pauses, and body movement beyond basic lip synchronization.
Text-Guided Scene & Action Control
Our OmniHuman API allows users to explicitly direct camera motion, character actions, timing and scene elements through text instructions for AI avatar generation.
Multi-Character & Multi-Audio Scene Generation
OmniHuman 1.5 AI API animates multiple characters within a single scene, each driven by independent audio tracks and coordinated interactions.
Long-Horizon Avatar Generation
OmniHuman 1.5 AI maintains motion coherence, expressiveness, and temporal consistency in video sequences exceeding one minute.
Diverse Character Styles & Appearance
OmniHuman supports a wide range of character styles and visual identities while preserving realism and expressiveness.
Temporal Identity Preservation
With pseudo last frame identity preservation technique, OmniHuman 1.5 prevents appearance drift across frames.
Multimodal Fusion Pipeline
Our OmniHuman 1.5 API jointly processes text, audio and visual inputs through shared attention mechanisms so each modality contributes optimally to the avatar generation.
Context-Aware Emotional Performance
OmniHuman API delivers emotionally rich animation by aligning motion, expression, and timing with semantic and contextual cues from audio and text.
SOTA Performance
OmniHuman-1.5 achieves superior results over leading academic baselines by leveraging a cognitive dual-system architecture.
