Introduction

ElatoAI is an innovative project enabling realtime AI voice agents on Arduino ESP32 devices. It integrates state-of-the-art AI voice models like OpenAI Realtime API, Gemini Live API, xAI Grok Voice Agent API, Eleven Labs AI Agents, and Hume AI EVI-4. This system allows for over 15 minutes of uninterrupted, globally accessible conversations, making it ideal for AI toys, companions, and various smart devices. The project leverages secure WebSockets and Deno Edge Functions to deliver low-latency, high-quality speech-to-speech interactions.

Installation

To get started with ElatoAI, follow these key steps:

  1. Clone the repository:

    git clone git@github.com:akdeb/ElatoAI.git

  2. Start Supabase: Install the Supabase CLI and Docker Desktop, then run supabase start from the root directory.

  3. Set up your NextJS Frontend: Navigate to frontend-nextjs, install dependencies (npm install), configure environment variables in .env.local, and run npm run dev.

  4. Choose Edge Server Option: You can use the hosted ElatoAI server (ELATO MODE) or run your own local Deno edge server (DEV MODE). For local setup, navigate to server-deno, configure .env with API keys, and run deno run -A --env-file=.env main.ts.

  5. Setup ESP32 Device Firmware: In firmware-arduino/Config.cpp, set ws_server and backend_server to your local IP address. Build and upload the firmware.

  6. Setup ESP32 Device Wifi: The ESP32 will create an ELATO-DEVICE captive portal. Connect to it and configure your Wi-Fi credentials via http://192.168.4.1.

  7. Turn on your device: After configuration, restart the ESP32 to connect to your Wi-Fi and server, enabling conversations with your AI character.
