Description:

With the help of terminal and some modules in Python through which one can shut down a PC by just using voice commands
Firstly, you have to input your voice command whether you want to shutdown your computer or not.
If "yes", it will shut down your computer; otherwise, it will not.
We have used three modules of Python here, pyaudio is working in the background and is necessary to be installed.

Procedure:

import os
import pyttsx3
import speech_recognition as sr

Then we will define one class, which have three functions namely takecommands(), Speak(), and quiteSelf().
takecommands():
- Using sr.Recognizer() it will recognise your voice and sr.Microphone() for input voice commands.
- Using r.recognize_google() it recognizes the language of the user, and check whether the language is en-in or not.
Speak():
- Using pyttsx3.init('sapi5') for voice recognition and synthesis.
- Using engine.getProperty('voices') for setting voice type and id.
- runAndWait() speech recognition Code Answer's. engine. say("I am the text spoken after changing the speech rate.")
quitSelf:
- Method to self shut down system.
