Problem

Smart-home control is usually app-bound. Voice over a normal phone call needs durable dialogue state and realtime device feedback.

Approach

  • Twilio IVR front door for natural voice commands
  • LangGraph conversation logic for multi-turn control
  • Socket.IO for live device state back to the session

Outcome

Hands-free home control from a phone call, with a clear path to more skills without rewriting the voice layer.
