Speech-driven 3D facial animation has emerged as a hot topic. During this process, movements in different facial regions are interdependent, influenced by the intricate interactions among facial muscles, and manifest personalized differences. The existing methods typically simplify the facial animation generation task to an infinitely thin surface skin deformation without an underlying structure, thereby ignoring the intricate and personalized dynamics of facial muscle activity. These methods tend to produce static or weak upper-face animations with an average facial movement style. In this work, we propose a novel framework, called DCPTalk, to mimic the intricate dynamics of facial muscle activity and portray personalized facial animations. Based on facial dynamic coupling properties, we propose Mouth2Face to simulate the facial muscle control system, yielding realistic and coordinated facial animations evoked by mouth movements. Mouth movements are easily synthesized from speech signals due to their direct correlation with phonetic articulation and vocal tract dynamics. To further enhance the detail of facial movements, we employ surface skin deformation to refine the facial animation derived from Mouth2Face. Furthermore, personal factors, including inherent physical traits and acquired speaking styles, directly determine the uniqueness and realism of facial animations. Inherent physical traits are embedded into Mouth2Face for constructing personalized facial muscle control system, while acquired speaking styles are employed to modulate external driving signals. Extensive qualitative and quantitative experiments as well as a user study indicate that DCPTalk outperforms the existing state-of-the-art methods.
