Yes, it is possible with the help of terminal and some modules in Python through which one can shut down a PC by just using voice commands
Required Modules:
- OS module: It is an in-built module in python that provides function for interacting with the operating system.
- Speech Recognition module: It is an external module in python whose functionality depends on the voice commands of the user.
- Pyttsx3 module: it is a text-to-speech conversion library in Python.
Installation:
pip install SpeechRecognition pip install pyttsx3
Role of Terminal:
In terminal there are many tags for the shutdown command, however we will use the /s tag with it to shut down the system.
Below are the steps to create a program to shut doe=wn PC using Voice Commands:
Step 1: Create a class Gfg and then create its methods, create takeCommands() method to take commands as input.
Python3
import SpeechRecognition as sr # Create class class Gfg: # Method to take voice commands as input def takeCommands(self): # Using Recognizer and Microphone Method for input voice commands r = sr.Recognizer() with sr.Microphone() as source: print('Listening') # Number pf seconds of non-speaking audio before # a phrase is considered complete r.pause_threshold = 0.7 audio = r.listen(source) # Voice input is identified try: # Listening voice commands in indian english print("Recognizing") Query = r.recognize_google(audio, language='en-in') # Displaying the voice command print("the query is printed='", Query, "'") except Exception as e: # Displaying exception print(e) print("Say that again sir") return "None" return Query |
Step 2: Create a Speak() method so that the computer can communicate with the user.
Python3
# Method for voice output def Speak(self, audio): # Constructor call for pyttsx3.init() engine = pyttsx3.init('sapi5') # Setting voice type and id voices = engine.getProperty('voices') engine.setProperty('voice', voices[1].id) engine.say(audio) engine.runAndWait() |
Step 3: Now create the quitSelf() to shut down the computer.
Python3
# Method to self shut down system def quitSelf(self): self.Speak("do u want to switch off the computer sir") # Input voice command take = self.takeCommand() choice = take if choice == 'yes': # Shutting down print("Shutting down the computer") self.Speak("Shutting the computer") os.system("shutdown /s /t 30") if choice == 'no': # Idle print("Thank u sir") self.Speak("Thank u sir") |
Step 4: Now in the driver code create a Gfg object and call the quitSelf() method.
Python3
# Driver code if __name__ == '__main__': # Creating gfg object Maam = Gfg() # Calling the methid to self shut down Maam.quitSelf() |
Below is the complete program to shut down a PC using voice commands:
Python
# Importing required modules import os import pyttsx3 import speech_recognition as sr # Creating class class Gfg: # Method to take coice commands as input def takeCommands(self): # Using Recognizer and Microphone Method for input voice commands r = sr.Recognizer() with sr.Microphone() as source: print('Listening') # Number pf seconds of non-speaking audio before # a phrase is considered complete r.pause_threshold = 0.7 audio = r.listen(source) # Voice input is identified try: # Listening voice commands in indian english print("Recognizing") Query = r.recognize_google(audio, language='en-in') # Displaying the voice command print("the query is printed='", Query, "'") except Exception as e: # Displaying exception print(e) # Handling exception print("Say that again sir") return "None" return Query # Method for voice output def Speak(self, audio): # Constructor call for pyttsx3.init() engine = pyttsx3.init('sapi5') # Setting voice type and id voices = engine.getProperty('voices') engine.setProperty('voice', voices[1].id) engine.say(audio) engine.runAndWait() # Method to self shut down system def quitSelf(self): self.Speak("do u want to switch off the computer sir") # Input voice command take = self.takeCommand() choice = take if choice == 'yes': # Shutting down print("Shutting down the computer") self.Speak("Shutting the computer") os.system("shutdown /s /t 30") if choice == 'no': # Idle print("Thank u sir") self.Speak("Thank u sir") # Driver code if __name__ == '__main__': Maam = Gfg() Maam.quitSelf() |
