A voice-controlled home automation system is a technological solution that allows users to interact with their home devices using voice commands. The system integrates various smart devices, such as thermostats, lights, security systems, and home entertainment systems (like music devices, TV's, etc..) and enables users to control them using voice commands via voice assistant. This system uses speech recognition and natural language processing to interpret voice commands and control the smart devices accordingly. In this paper, we have been reading several research papers and had written an extract of that research papers.
