Realtime AI Conversational 3D Avatar + Lip-Sync

Unity project for a 3D conversational avatar with STT, chat, TTS, lip sync, latency telemetry, and a world-space debug panel. The goal is to keep clear architecture, observable flow, and credentials out of the code.

Real-time AI Conversation with Lip-Sync.

It’s a system for Unity that allows for real-time conversations with a 3D (VR enabled) avatar, syncing its lip movements with AI-generated audio.

The code integrates:

  • Voice processing and audio streaming.
  • Lip-sync animation synchronization.
  • A foundation for anyone looking to experiment with conversational avatars in VR.

The goal was to explore how to make VR interactions feel a bit more natural.

The repository is public, so if you’re interested, feel free to check out the code, use it, or suggest improvements. All feedback is welcome.
