Voice control-based systems have become the ubiquitous means of communicating with smart devices all thanks to the advances in the domain of Internet of Things. This has led to massive expansion in adoption of home automation systems by many households. In this paper, a speech recognition-based module is utilized to record and process the voice-based speech commands, that are converted to text data. The Node MCU system with Bluetooth connectivity serves to handle the voice commands and allows for controlling of gadgets such as lights. The Node MCU based microcontroller system utilizes the natural language processing techniques to create a voice-activated home automation system allowing the house owners to operate a variety of electric and electronic gadgets and appliances. The Node MCU connects with the respective applications using communication protocols.
