Website Home (ChinaZ.com) June 17 News: Hallo enables the generation of singing and talking videos from a single image and audio input, while also controlling the expressions and postures of the characters in the video. This technology is based on a hierarchical audio-driven visual synthesis method using diffusion models, aiming to enhance the alignment accuracy between speech input and generated animation, including synchronization of lips, expressions, and postures.
Key Features:
Virtual Character Animation Generation: Generate realistic, dynamic virtual character animations through voice audio input, achieving precise synchronization of lip movements, expressions, and postures.
Real Character Animation Generation: Apply this technology to real people, and the generated animations accurately reflect the expressions and movements of real individuals.
Multiple Motion Controls: Provide precise control over character expressions, postures, and lip movements, supporting adaptive control of various expressions and postures to enhance the diversity and authenticity of animations.
Cross-Actor Application: Support the generation of personalized animations for different identities, creating animations tailored to different character identities through audio input.
Singing Animation Generation: Generate synchronized singing animations through voice and song audio input, accurately reflecting the lip movements and expressions during singing.
This technology generates animations of lip synchronization, expression changes, and posture changes from voice input, improving the alignment accuracy between voice and generated animations, making the lips, expressions, and postures of the animations more aligned with the voice. The advanced technology and structure enhance the real-time performance and visual effects of animation generation, making the generated animations more realistic and natural.
The results of this research are not only innovative academically but also demonstrate significant potential in practical applications, such as in entertainment, education, virtual assistants, and other multimedia fields. Through this technology, users can interact more intuitively and vividly with virtual characters, enjoying a richer and more authentic experience.
