Description

Abstract: Voice command recognition systems are increasingly becoming integral to domestic and industrial automation, offering a more user-friendly alternative to conventional control panels, which can be complex and difficult to operate. Additionally, many institutions and households in rural areas still rely on manual control systems due to the absence or unreliability of internet connectivity. This research focuses on designing and implementing a user-friendly, voice-controlled smart home automation system to address these limitations. Besides, Traditional home systems primarily depend on manual operation for appliances such as lighting, security alarms, and heating systems, which can be inconvenient and energy-inefficient. This challenge is particularly significant for older people and individuals with disabilities. The proposed system enhances convenience, accessibility, and energy efficiency by enabling voice control of essential household devices, including lighting, air conditioning, and televisions. Unlike many existing solutions, the system operates reliably without an internet connection, making it more affordable and practical. However, the proposed design consists of key components, including a microcontroller as the central processing unit, a voice recognition module, a relay circuit, and auxiliary components. To optimise the design performance, the system was modelled and simulated using Proteus software, allowing for thorough testing before physical implementation. The functionality was programmed in C++ to ensure seamless interaction between components. A prototype was developed and experimentally tested, demonstrating minimal response time delay between simulation and implementation, as well as high command accuracy. Performance analysis, including response time and accuracy, was conducted to evaluate the system’s effectiveness in achieving the research objectives.
