Speech Driven Animation

Speech-driven animation aims to realistically animate 3D facial models based solely on audio input, focusing on accurate lip synchronization and expressive facial movements. Current research emphasizes improving model efficiency and robustness using architectures like transformers and neural radiance fields, often incorporating techniques like low-rank adaptation and disentanglement of content and style to enhance control and personalization. This field is crucial for applications ranging from virtual characters in entertainment and gaming to more realistic human-computer interaction and the creation of synthetic training data for other AI models, particularly where real data is scarce or restricted.
