Overview
Duix.Avatar clones a person's face and voice from a short video, then renders lip-synced videos driven by text or audio. It runs as an Electron client plus Docker services for ASR (fun-asr), TTS (fish-speech-ziming) and video synthesis, all on a local NVIDIA GPU. The services expose local HTTP endpoints for voice synthesis (port 18180) and video synthesis (port 8383).
Who it is for: Creators and developers wanting local avatar video generation on an NVIDIA GPU
Ranked among open-source alternatives to HeyGen (#3 of 3).

- Scripts supported in eight languages, including English, Chinese, Japanese and Spanish
- Clients for Windows (installer) and Ubuntu 22.04 (AppImage); lite compose file available
Weaknesses
