KDTalker++: Controllable Talking Portrait Generation with Audio, Text, and Expression Editing

摘要

This work presents KDTalker++, a real-time system for generating talking portrait videos from a single image using audio or text input. Built on a keypoint-based spatiotemporal diffusion model, it adds voice cloning, background editing, and fine-grained expression control. The demo is available at https://kdtalker.com.
