ElatoAI vs xiaozhi-esp32-server
ESP32 voice AI projects compared
ElatoAI and xiaozhi-esp32-server both connect ESP32 devices to voice and AI services. ElatoAI combines device firmware, edge or FastAPI server options, and a web app, while xiaozhi-esp32-server focuses on a self-hosted backend for compatible xiaozhi-esp32 devices.
ElatoAI: Build Realtime Voice AI Devices with ESP32
ElatoAI connects ESP32 devices to realtime speech-to-speech AI through secure WebSockets and edge servers. It suits makers building conversational toys or devices who can work with Arduino firmware, cloud services, and external AI model providers.
xiaozhi-esp32-server: Run a Voice-AI Backend for ESP32 Devices
A self-hostable backend for xiaozhi-esp32 voice-enabled hardware, with speech, language-model, device-control, and management features. It suits builders who want to configure their own ESP32 service and connect AI providers, but the project warns against production use.
