# Build a Voice AI Agent with Twilio Agent Connect and Gemini Flash


- **Date:** Friday, Sep 25, 2026
- **Time:** 12:30–14:30 (120 min)
- **Room:** Stage 8
- **Event:** World Congress 2026 North America

## Description

You will build a working voice AI agent from scratch in under 120 minutes. Using Twilio Agent Connect as the middleware layer and Google Gemini Flash as the LLM, you will write a single message handler and get a real phone call answered by an AI agent. No boilerplate, no glue code — TAC handles WebSockets, webhooks, and conversation routing so you can focus entirely on the agent logic. You will leave with a running local app, a configured Twilio number, and the mental model to extend it with tools, handoffs, and custom personas. Both Python and Node.js paths are supported.
