Phase 5 — Advanced Integration

Objective

Use the Gemini Live API (real-time streaming multimodal) to enable live voice conversations with Timmy in The Nexus.

Design

  • User speaks via browser microphone → audio streamed to Live API
  • Gemini processes speech + current context (room, agent state)
  • Response streamed back as text + audio simultaneously
  • Timmy's avatar reacts in real-time (lip sync, gestures)

Acceptance

  • Build a WebRTC/WebSocket audio capture module in the browser
  • Implement Live API streaming client in the backend
  • Wire Timmy's system prompt (SOUL.md) into the Live API session
  • Add push-to-talk and hands-free modes to the Nexus HUD
  • Implement response audio playback via Web Audio API
  • Test latency: target < 500ms first-byte response time

Notes

This is the highest-complexity integration. Requires careful audio handling and may need a dedicated server-side proxy.

API Ref

  • Live API docs: ai.google.dev/gemini-api/docs

Audit: Google AI Ultra integration epic — these are aspirational proposals, not scoped work. Closing. Reopen individually with acceptance criteria if needed.
