Voice recognition, Smart homes, Home automation, IoT, Arduino Uno, MCU node, GSM, Security, Home automation is increasingly becoming a fundamental part of modern living, offering convenience, efficiency, and security. The ability to automate everyday household tasks reduces human effort, enhances security, and promotes energy efficiency. This study explores the challenges and possibilities of smart home automation, emphasizing the need for easy-to-use and effective control mechanisms.The study proposes a voice recognition-based system to enhance the smart home experience, leveraging the Internet of Things (IoT) and machine learning. Voice control provides an intuitive and adaptive approach to home automation, improving accessibility for all users. This paper also examines various control methods, including Dual-Tone Multi-Frequency (DTMF), speech recognition, Wi-Fi-based automation, and GSM-enabled systems.This research highlights key challenges in implementing voice-controlled smart home automation, such as affordability, security, connectivity, and eco-friendliness. The proposed model integrates Automatic Speech Recognition (ASR) to optimize smart home interactions, demonstrating improved user experience and security. The study envisions a future where smart homes are intelligent, adaptive, and responsive to user needs..
