Heygem - Open-source digital human model launched by Silicon Intelligence

What is Heygem

Heygem is an open-sourcedigital human modellaunched by Silicon Intelligence, designed specifically for the Windows system. Based on advanced AI technology, it only needs 1 second of video or 1 photo to complete the digital human image andvoice cloningwithin 30 seconds, and synthesize a 4K ultra-high-definition video within 60 seconds. Heygem supports multilingual output, multiple expressions and movements, and has 100% lip-sync matchingcapability, maintaining a highly realistic effect under complex lighting or occlusion scenarios. Heygem is based on a fully offline operation mode, protecting user privacy, supporting low-configuration hardware deployment, greatly reducing the threshold for use, and providing efficient, low-cost digital human solutions for content creation, live streaming, education, and other scenarios.

Heygem's main features

• Second-level cloning: Only 1 second of video or 1 photo is needed to complete the cloning of the digital human image and voice, completing the clone within 30 seconds, and synthesizing a 4K ultra-high-definition digital human video within 60 seconds.
• Efficient inference: The inference speed reaches 1:0.5, and the video rendering and synthesis speed reaches 1:2.
• High-quality output: Supports 4K ultra-high-definition, 32 frames/second video output, surpassing the 24-frame standard of Hollywood movies.
• Multilingual support: The cloned digital human supports output in 8 languages, meeting the needs of the global market.
• Unlimited cloning: Supports unlimited cloning of digital human images and voices, and unlimited video synthesis.
• 100% lip-sync matching: Achieves highly realistic lip-sync matching under complex lighting, occlusion, or side-angle conditions.
• Runs on low configuration: Supports one-click Docker deployment, and can run with only an NVIDIA 1080Ti graphics card at minimum.

Heygem's technical principles

• Voice cloning technology: Based on advanced technologies such as AI, it generates a voice similar or identical to a given voice sample, covering the context, intonation, speed, and other aspects of speech.
• Automatic speech recognition: Converts the vocabulary content in human speech into computer-readable input, allowing computers to "understand" what people say.
• Computer vision technology: Visual processing used in video synthesis, including facial recognition, lip analysis, etc., ensuring that the virtual avatar's lip movements match the voice and text content.
