The present invention discloses a high-fidelity voice-driven
digital human synthesis method based on 3DGS. First, a static
digital human model is trained, constructed based on 3D
Gaussian Splatting, and the
image quality is improved using a spatial
discriminator to capture the basic shape and appearance of the
digital human. Subsequently, a dynamic driving network is trained, which includes an optimizable global prompt, a progressive conditional attribute prediction
network module, and a dual
discriminator architecture. Among them, the optimizable global prompt module is used to stabilize the
facial geometry of the digital human and prevent drift during the
animation process; the progressive conditional attribute prediction
network module is used to efficiently and temporally coherently predict the dynamic
Gaussian parameters of the digital human model; the dual
discriminator architecture module is used to improve the realism and
temporal consistency of the synthesized digital human
animation. The present invention is applicable to voice-driven digital human
animation synthesis, can effectively improve the realism, efficiency, and structural coherence of the synthesized digital human animation, and achieve real-time rendering.
