Abstract:- This paper illustrates anon-traditional approach to system control focused on speech recognition usingmobile apps and MATLAB. In all ways, life is becoming simple and simple withadvancement in technology. New research is currently going on in every field toboost device efficiency and to make work simpler than previous ones. Automaticsystems are favored over manual systems in today's world. One of them is speechrecognition based interface control. It consists of a Wi-Fi control board, arelay circuit and a Smartphone app. This allows devices to be operated by usersby just sitting in one position. A significant advantage of this method is thecontrol of machines, i.e. making them on and off as per user requirements. Thisuser can save as well as discourage excessive use of energy by using it. Deviceaccess is restricted to a single user, so that protection is not compromised.
