使用语音命令关闭电脑的Python脚本

是的，可以借助终端和Python中的一些模块，通过这些模块，只需使用语音命令就可以关闭 PC

所需模块：

• OS模块：它是Python中的一个内置模块，提供与操作系统交互的函数。
• 语音识别模块：它是Python中的一个外部模块，其功能取决于用户的语音命令。
• Pyttsx3 模块：它是Python中的文本到语音转换库。

安装：

pip install SpeechRecognition
pip install pyttsx3

终端的作用：

在终端中有许多用于关闭命令的标签，但是我们将使用/s标签来关闭系统。

以下是使用语音命令创建关闭 doe=wn PC 的程序的步骤：

步骤1：创建一个类Gfg ，然后创建它的方法，创建takeCommands()方法以将命令作为输入。

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

第 2 步：创建一个Speak()方法，以便计算机可以与用户进行通信。

# 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()

第 3 步：现在创建quitSelf()来关闭计算机。

蟒蛇3

# 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")

第 4 步：现在在驱动程序代码中创建一个Gfg对象并调用quitSelf()方法。

蟒蛇3

# Driver code
if __name__ == '__main__':
     
    # Creating gfg object
    Maam = Gfg()
     
    # Calling the method to self shut down
    Maam.quitSelf()

以下是使用语音命令关闭 PC 的完整程序：

          with sr.Microphone() as source:
              print('Listening')
 
              # Number pf seconds of non-speaking audio before

          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")

            self.Speak("Shutting the computer")
            os.system("shutdown /s /t 30")

            self.Speak("Thank u sir")

if __name__ == '__main__':
    Maam = Gfg()
    Maam.quitSelf()

输出：
