Voice-controlled automation systems are gaining popularity in smart home technologies due to their convenience and ease of use. This project presents a Voice Assist ESP system, which enables users to control multiple electrical appliances using voice commands. The system is built around the ESP32 WROOM microcontroller, which acts as the central processing unit. Voice commands such as fan on/off, LED on/off, buzzer on/off, and light on/off are given through a smartphone application and transmitted to the system using the HC-05 Bluetooth module. The ESP32 receives these commands and processes them to control different appliances connected through a 4-channel relay module. The received command and device status are displayed on a 16×2 LCD display to provide real-time feedback to the user. Additionally, the ESP32 utilizes its built-in Wi-Fi capability to upload device status and command data to a cloud IoT platform, enabling remote monitoring and data logging. The proposed system offers a cost-effective, reliable, and user-friendly solution for smart automation. It improves convenience and accessibility, especially for elderly or physically challenged individuals, by allowing hands-free control of household appliances.
