DreamTalk: Generating Realistic Talking Heads with AI and Expressive Facial Expressions
An innovative project that aims to enable AI to make faces talk while maintaining realistic facial expressions is the focus of DreamTalk. This project introduces a Diffusion-based Expressive Talking Head Generation Framework, developed by a team consisting of researchers from Tsinghua University, Alibaba Group, and Huazhong University of Science and Technology. The framework leverages diffusion models to generate expressive talking heads with high-quality audio-driven face motions and accurate lip-sync capabilities across various expressions.
The DreamTalk Framework Components
The DreamTalk framework comprises three essential components: a denoising network, a style-aware lip expert, and a style predictor. These components work together to enhance the expressiveness and realism of the generated talking heads.
1. Denoising Network
The diffusion-based denoising network plays a crucial role in synthesizing high-quality audio-driven face motions while maintaining consistency across different facial expressions. This component ensures that the generated faces talk realistically by effectively processing audio inputs into corresponding facial movements.
2. Style-Aware Lip Expert
To improve the accuracy of lip motions and ensure proper lip-syncing, DreamTalk incorporates a style-aware lip expert. This component is designed to guide the movement of lips in synchronization with speech patterns while considering various speaking styles for more natural-looking results.
3. Style Predictor
Innovatively eliminating the need for reference videos or text for expression guidance, an additional diffusion-based style predictor is integrated into DreamTalk. This predictor aids in forecasting target styles for generating expressive talking heads without relying on external references.
Moshi AI by Kyutai – A Voice-Enabled Conversational AI Model
