Abstract

Virtual assistant is used to run machines like laptop or Personal computer (PC) on the command given by the user. Virtual assistant is an application program that understands natural language and voice commands to complete the tasks for the users. Virtual assistant is used to perform a typical task like showing date and time, managing emails and open apps based on the voice command. Now a days virtual assistant is very useful to human being. It makes human life easier like operate PC or laptop based on only voice command. Virtual assistant is less time consuming. By using virtual assistant, we can save our time and get engaged in other works. There are several voice assistants in market like Siri for apple TV remote, Google Assistant for pixel XL smartphones, Alexa is a smart speaker which is developed using Raspberry Pi, Microsoft Cortona for windows 10. Just like these all-virtual assistants we will developing a virtual assistant for windows. We use Artificial Intelligence technology for this work. Also use python as a programming language because python offers a good collection of libraries. For this software we use microphone as input device to receive voice requests from user and speaker as output device to give the output voice. This process is the combination of several different technology like voice recognition, voice analysis and language processing. Virtual assistant uses Natural language Processing to match user text or voice input to executable commands.
