Silicon Intelligence Digital Human
An open-source tool for creating and interacting with digital humans in real time, helping developers and educators build custom, lip-synced virtual characters for language learning, live streams, and virtual companionsh
Tool overview
Built on the open-source DUIX project, Silicon Intelligence provides a full stack for digital human creation and real-time interaction. It supports voice and visual multimodal input, runs at up to 50 FPS, and maintains accurate lip-sync even under complex lighting and partial occlusion, with output in 8 languages. A single Docker command enables local deployment, and over 50 preset digital human roles are available, along with custom prompt definitions—making it easy to craft virtual girlfriends, teachers, lawyers, and more.
Its advantages lie in open-source transparency and modest hardware requirements. A local offline installation requires only an NVIDIA GeForce RTX 3060 Ti, protecting user privacy. The precise lip-sync, multilingual support, and role customization make it practical for tutoring, live interaction, and emotional companionship; mobile deployment is as simple as a few lines of code.
Limitations are notable.
