Voice Controlled Home Automation Using ESP32 and IoT-Based Cloud Integration

Abstract: The convergence of voice recognition technologies and the Internet of Things (IoT) is fundamentally reshaping smart home automation, moving it towards more intuitive and accessible human-machine interfaces. This paper presents the design, implementation, and rigorous evaluation of a robust, cost-effective, voice-controlled home automation system. The proposed system leverages the computational capabilities of the ESP32 microcontroller and integrates seamlessly with major cloud-based voice services, namely Google Assistant and Amazon Alexa. User voice commands are processed by these assistants and routed to the ESP32 via the MQTT (Message Queuing Telemetry Transport) protocol, a lightweight and…
