This program consists of if else(conditional statements). It is a basic programs for people who are moderate in programming and has some experience in it. We have also used try and catch statements. As a whole it is created as a competitive programming type. We are using many libraries also like pyttsx3 and speech recognition library which will convert the voice into string so that machine can understand it by converting that string in binary language and so when machine replies the same action is carried for machine also.
