Automation is an upcoming technology of 21st century. The important reason automation gaining its popularity is reducing human effort, interaction and to reduce human errors. With the improvement in latest technologies, smartphones have become an essential gadget to all. For 2016, the number of Smartphone users is forecast to reach 2.1 billion. Another upcoming technology is the natural language processing which uses human voice for commands. Combining all of these technologies, the project presents a wireless voice controlled home automation system. Such a system will be helpful for senior citizens and physically disabled persons who are in need

2.1. System Components
2.2. Figure 1: Architecture Diagram of the System
The Voice-operated Android and Arduino Home automation system uses an Android based Bluetooth enabled phone for its application and the Arduino Uno as the microcontroller. The key components of this system are:
• Android Smartphone
• Arduino UNO board
• ESP8266 Wi-Fi module
• Relays
• Light bulbs / LED’s

2.2.1. Android Based Phone
Android is a mobile operating system (OS) based on the Linux kernel and currently developed by Google. With a user interface based on direct manipulation, the OS uses touch inputs that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard. We have used the Android platform because of its huge market globally and it’s easy to use user interface. Applications on the Android phones extend the functionality of devices and are written primarily in the Java programming language using the Android software development kit (SDK). The voice recognizer which is an in built feature of Android phones is used to build an application which the user can operate to automate the appliances in his house.
2.1.2 Arduino
Arduino is an open source prototyping platform easy to use on software as well as hardware. The board can programmed to switch on/off electronic appliances using ARDUINO (IDE).
