Control of Electrical Appliances through Voice Commands

Abstract

Voice recognition is an expanding trend nowadays for automation. As speech is the preferred mode of operation for human being, this paper highlights the importance of human voice that activates electrical appliances at home in wireless environment. The user makes use of voice commands to perform certain actions such as switching the lights ON/OFF and regulating the speed of appliances. This system plays an important role for the elderly and physically disables people to control their appliances in intuitive and flexible way. The graphical user interface (GUI) system is developed using LabVIEW. LabVIEW is a highly productive development environment that interacts with real-world data for creating custom applications. So the method of control of electrical appliances is implemented using LabVIEW. With this voice recognition technique accuracy of more than 90% is achieved.
