I built a 3D AI academic advisor that talks back in real-time — here's how it works.
Most AI chatbots are boring text boxes. I wanted to build something that actually feels alive.
Meet TUF Avatar Talk — a 3D animated academic advisor with real-time voice conversation, lip-sync, and natural responses powered by Google Gemini.
The stack:
→ React Three Fiber for the 3D avatar
→ FastAPI backend with WebSockets for real-time streaming
→ Google Gemini for conversation
→ Custom lip-sync engine tied to audio output
What it does:
You speak → it listens → Gemini thinks → the avatar responds with synced lip movement and voice, all in real-time. No reload, no waiting.
The hardest part wasn't the AI — it was getting the latency low enough that the conversation feels natural. WebSockets streaming + chunked audio playback was the answer.
