Espressif Systems’ EchoEar is a compact ESP32-S3 AI chatbot designed for voice interaction and edge AI applications, for smart toys, voice-enabled speakers, and control systems. It features a 1.85-inch circular touch display, a dual microphone array with local wake-word detection, and support for large AI models from OpenAI, Xiaozhi AI, and Gemini.
