Introduction

 In this technological era, everything that man can do is replaced by machines. One of the main reasons is the performance change. In today's world, we train our machines to think like humans and do its task by themselves. That's why the concept of a virtual assistant came about.

A virtual assistant is a digital assistant that uses voice recognition functions and language processing algorithms to recognize the user's voice commands and perform the relevant tasks according to the user's requests. Based on specific commands given by the user, the virtual assistant is able to filter out ambient noise and return relevant information.

Virtual assistants are completely software, but these days they are integrated into various devices, and also some assistants are designed specifically for individual devices, such as Alexa. Due to drastic changes in technology, now is a. high time to train our machine using machine learning, deep learning, neural networks. Today, we can talk to our machine using a voice assistant. Today, every big company uses Voice Assistant so that their user can take help from the machine through their voice. So with the voice assistant, we're taking it to the next level where we're able to talk to our machine.
