XiaoZhi-Compatible ESP32 Voice Assistant Starter Guide

This guide packages the popular China XiaoZhi-style ESP32 voice assistant workflow for English-speaking makers. It is based on the public open-source ecosystem around ESP32 voice AI, MCP-style device control, and low-cost ESP32-C3/S3 hardware.

What This Build Does

The device acts as a small voice interface: microphone input, speaker output, Wi-Fi connection, wake/interaction button, and a cloud or local AI backend depending on firmware choice.

Recommended Kit

• ESP32-C3 or ESP32-S3 voice AI board
• I2S microphone or onboard mic
• Speaker and amplifier path
• Battery or USB-C power
• 3D printed or acrylic enclosure
