DESIGN AND CONSTRUCTION OF A VOICE-ACTIVATED SWITCHING SYSTEM (VASS)

This project aims to develop an innovative voice-activated switching system that enhances home automation by enabling hands-free control of electrical appliances. Utilizing speech recognition technology and the Arduino Uno microcontroller, the system provides users with a seamless and accessible method of operating household devices through voice commands. The project is built around an Arduino Uno interfaced with a Speech Recognition Module Easy VR3 plus, a relay module, and a 5V converter module, all housed within a protective enclosure. The Speech Recognition Module captures and processes voice commands, which are then interpreted by the Arduino Uno. Based on the received command, the Arduino activates the relay module, which switches the connected electrical appliances on or off. The system is powered by a 12V dc battery, regulated to 5V using an L298D motor driver to ensure stable operation. The developed voice-activated switching system successfully demonstrated the capability to recognize and execute voice commands efficiently. The Speech Recognition Module accurately processed user input, and the Arduino Uno effectively translated the recognized commands into control signals for the relay module. The system exhib ited high response accuracy in quiet environments and maintained reliable performance under various conditions. Ultimately, this project achieved its goal of creating an affordable, user-friendly, and accessible voice-controlled home automation solution
