Innovations in Voice-Controlled Smart Home Technology: Exploring AI Roles and Future Potential

The Internet of Things (IoT) domain. This paper explores the evolving landscape of voicecontrolled smart home

technology, focusing on the integration of artificial intelligence (AI) and its future potential in creating intelligent, contextaware environments. The proposed system demonstrates a cost-effective and scalable smart home prototype built using Node

MCU ESP32, a powerful microcontroller with built-in Wi-Fi capabilities. Voice commands processed through AI-driven

platforms such as Google Assistant are used to control various home appliances and monitor environmental conditions,

showcasing real-time automation through the IoT. Key components of the system include a 1-Channel Relay Module for

switching high-voltage devices, a DHT11 sensor for monitoring temperature and humidity, and a 16x2 LCD to visualize sensor

data. The setup also integrates a cooling fan and a light strip, both controlled via voice input, to provide environmental

adjustments based on user preferences and sensor feedback. AI and Natural Language Processing (NLP) modules enable

intuitive voice-based interactions, allowing users to perform tasks such as turning on the fan when temperatures exceed.
