Voicing Your Emotion: Integrating Emotion and Identity in Cross-Modal 3D Facial Animations
Wenfeng Song, Zhenyu Lv, Xuan Wang, Xia Hou · 2024
Recent advances in speech-driven 3D facial animation have yielded promising results, yet capturing intricate expressiveness, particularly in emotion and identity, remains an intricate challenge. Addressing this deficiency, we unveil a pioneering method tailored to produce 3D facial expressions that resonate deeply with emotion and identity, guided by speech and user-provided prompt words. Our key insight is an emotion-identity fusion mechanism, a pre-trained self-reconstruction codebook, meticulously crafted from a wide array of emotional facial movements, serving as an expressive motion benchmark. Using this foundation, prompt words are seamlessly transformed into facial representations that capture both emotion and identity, and are then adeptly projected onto 3D templates. Our approach emerges as a robust tool for crafting 3D talking avatars, rich in emotional depth and distinctive identity.
