Wizstar's two-stage pipeline fixes lip-sync and stability issues in AI avatars
Med1_Ai · x · 2026-08-26
Most AI avatars still struggle with lip-sync breaks during head turns, unstable faces when partially covered, and robotic movements. Wizstar's approach stands out by using a two-stage, audio-driven animation pipeline:
- Separates speech, mouth motion, and head pose into independent signals
- Reconstructs facial textures and expressions afterward for greater realism and stability
This architecture maintains accurate lip-sync even when the mouth is obscured, camera angles change dramatically, or movements are fast. Impressively, the avatars don't just talk—they gesture, interact with objects, and move more like real presenters.
