Achieving state-of-the-art lip-sync accuracy while maintaining natural expressiveness, ReFree-S2V redefines the standards for speech-driven character animation.
Semantic motion anchors enable a dramatic 8.2% boost in text-to-gesture retrieval accuracy by grounding gesture motion in communicative intent, not just kinematics.
Finally, realistic and expressive full-body gestures for conversational agents can be generated in real-time, thanks to a novel causal framework that models both temporal dynamics and part-level motion hierarchy.
