Build an AI Voice Agent That Actually TALKS BACK 🤖🗣️ (Twilio + ElevenLabs Tutorial)

Ever wanted to build an AI that can actually answer phone calls and have a real conversation? 🎙️

In this Part 2 of my AI Voice Agent series, I walk you through connecting ElevenLabs Conversational AI to Twilio to create a fully functional voice agent that can TALK BACK!

🔥 What You'll Learn

This tutorial covers building a bidirectional audio bridge where:

• Twilio captures phone audio and streams it to your server


• Your server forwards audio to ElevenLabs for transcription & AI processing


• ElevenLabs generates natural speech responses


• The AI voice is sent back through Twilio to the caller

It's like having your own AI assistant that can answer calls 24/7!

📚 Topics Covered

• Setting up ElevenLabs Agent


• Creating & configuring a new AI agent


• Choosing the right Voice & TTS Model


• Selecting the best LLM (speed matters!)


• ⚠️ Critical: Audio format configuration


• WebSocket connection setup
