Shutdown Computer with Voice Using Python

by anupmaurya

In this article, you’ll learn to make a python program to Shutdown Computer with Voice commands. This assistant can talk to you or communicate with you using your voice and listens to your voice.

Required Modules

1. PyAudio

PyAudio provides Python bindings for PortAudio v19, the cross-platform audio I/O library. With PyAudio, you can easily use Python to play and record audio on a variety of platforms, such as GNU/Linux, Microsoft Windows, and Apple macOS. To install pyaudio, go to terminal and type,

pip install pyaudio

2. SpeechRecognition

It is an external module in python whose functionality depends on the voice commands of the user. To install SpeechRecognition, go to terminal and type,

pip install speechrecognition

3. Pyttsx3 

It is a text-to-speech conversion library in Python. To install Pyttsx3, go to terminal and type,

pip install pyttsx3

Code with comments

# Importing required modules
# importing pyttsx3
import pyttsx3
# importing speech_recognition
import speech_recognition as sr
# importing os module
import os

# creating take_commands() function which
# can take some audio, Recognize and return
# if there are not any errors
def take_commands():
    # initializing speech_recognition
    r = sr.Recognizer()
    # opening physical microphone of computer
    with sr.Microphone() as source:
        r.pause_threshold = 0.7
        # storing audio/sound to audio variable
        audio = r.listen(source)
            # Recognizing audio using google api
            Query = r.recognize_google(audio)
            print("the query is printed='", Query, "'")
        except Exception as e:
            print("Say that again sir")
            # returning none if there are errors
            return "None"
    # returning audio as text
    import time
    return Query

# creating Speak() function to giving Speaking power
# to our voice assistant
def Speak(audio):
    # initializing pyttsx3 module
    engine = pyttsx3.init()
    # anything we pass inside engine.say(),
    # will be spoken by our voice assistant

Speak("Do you want to shutdown your computer sir?")
while True:
    command = take_commands()
    if "no" in command:
        Speak("Thank u sir I will not shut down the computer")
    if "yes" in command:
        # Shutting down
        command.Speak("Shutting the computer")
        os.system("shutdown /s /t 30")
    Speak("Say that again sir")

We have used three modules of Python here, pyaudio is working in the background and is necessary to be installed.

Here, we have made the take_command() function so that it can be used here as the ear of our voice assistant in Python which ultimately uses the speech_recognition module.

Similarly, we have made the Speak() function so that it can be used here as the mouth of our voice assistant in Python which ultimately uses the pyttsx3 module.
