Abstract
The present disclosure discloses a speech-driven facial animation generation method. The method is mainly divided into six steps: extracting speech features, collecting frequency information, summarizing time information, decoding action features, driving a facial model, and sliding a signal window. The present disclosure can drive, according to an input speech audio signal, any facial model in real time under a particular delay to generate animation. The quality of the animation reaches the currently most advanced speech animation technology level, and has the characteristics of light weight and good robustness. The present disclosure can be used to generate speech animation under different scenes, such as VR virtual social networking, and virtual speech assistants and games.
