This paper presents the design and implementation of an offline voice-controlled home automation system using the VC-02 speech recognition module and Arduino Uno microcontroller. The system enables users to control electrical appliances such as a fan and light using predefined voice commands without the need for internet connectivity. The proposed solution focuses on low-cost implementation, ease of use, and reliability. The VC-02 module processes voice commands locally and sends corresponding signals to the microcontroller, which in turn controls relay modules to operate the appliances. The system is particularly useful in environments where internet access is limited or unavailable. The design ensures user safety and energy efficiency while providing a simple and scalable home automation solution.
