Design and Construction of a Voice Control Automation System

Electrical and Electronics Engineering

System automation is a trending research area in the 21st century considering its important role in our daily lives. The main importance of an automated system is the fact that it reduces human stress and error. There has been a sudden shift from the normal switches to the remote based control switches in recent times. Presently, conventional wall switches located in different parts of the house makes it difficult for operation more especially the elderly and physically challenged people. Technological advancement has made it easier and necessary that every human being should own a mobile smart phone. Applications are being developed on Android systems that are useful in various ways. Another upcoming technology is natural language processing which enables the command and control of systems using voice. This research work presents a Micro Controller-based Voice Control Automation System using Android Smartphone. This system can enable users to have absolute control over every appliance in the house using their voices. The control circuit consists of an Arduino Uno microcontroller, which processes the user commands using voice via android smartphone which is installed with ‘AMR voice’ application. The relay controls the switching of devices while the Bluetooth Module shares signal data having establish a wireless connection between the microcontroller and the smartphone.
