使用语音识别重新启动计算机

我们可以在Python的帮助下做到这一点。 Python有很多库可以帮助很多事情变得容易。我们需要终端的帮助来完成这项任务。 Python 最好的库之一语音识别将帮助我们做到这一点。

所需模块

• Pyttsx3：这是Python中的文本到语音库。我们必须使用pip。

pip install pyttsx3

• 语音识别模块：该模块将帮助我们识别给计算机的语音和命令。我们必须使用 pip 来安装语音识别。

pip install SpeechRecognition

• OS模块： Python中提供与操作系统交互函数的模块。 OS 模块随Python包一起提供。点子不是必需的。

为什么使用终端？

当我们在终端中键入 shutdown 时，我们将获得许多选项，借助这些选项，我们可以重新启动计算机。因为我们将有很多标签。我们可以使用“/r”和关闭来重新启动。

带有关机命令的终端。我们可以看到 /r 表示完全关闭和重新启动。

循序渐进的方法：

步骤 1：我们必须使 Speak函数使计算机与我们进行通信。

Python3

# Method to give 
# output voice commands 
def Speak(self, audio):
    engine = pyttsx3.init('sapi5')
     
    # initial constructor of pyttsx3
    voices = engine.getProperty('voices')
     
    # getter and setter method
    engine.setProperty('voice', voices[1].id)
    engine.say(audio)
    engine.runAndWait()

第 2 步：我们现在必须创建一个函数来接收我们的命令。

# Method to take
# input voice commands
def take_commands(self):
      r = sr.Recognizer()
     
    # Making the use of Recognizer
    # and Microphone method from
    # Speech Recognition for taking commands
    with sr.Microphone() as source:
          print('Listening')
        r.pause_threshold = 0.7
        # seconds of non-speaking audio
        # before a phrase is considered complete
        audio = r.listen(source)
        try:
            print("Recognizing")
            Query = r.recognize_google(audio, language='en-in')
             
            # For listening the command in indian english
            print("the query is printed='", Query, "'")
             
            # For printing the query or the
            # command that we give
        except Exception as e:
             
            # This is for printing the exception
            print(e)
            print("Say that again sir")
            return "None"
    return Query

第 3 步：现在我们将制作一个 Restart 方法来使计算机重新启动。

蟒蛇3

# Method to restart PC
def restart(self):
    self.Speak("do u want to restart the computer sir")
    take = self.takeCommand()
    choice = take
    if choice == 'yes':
        print("Restarting  the computer")
        self.Speak("Restarting the computer")
        os.system("shutdown /r /t 30")
    if choice == 'no':
        print("Thank u sir")
        self.Speak("Thank u sir")

第 4 步：现在我们将拥有 main 方法。

蟒蛇3

# Driver Code
if __name__ == '__main__':
    Maam = Main()
    Maam.restart()

以下是上述方法的完整程序：

蟒蛇3

# Import required modules
import pyttsx3
import time
import speech_recognition as sr
import os
 
 
 
# Creating class
class Main:
     
    # Method to give output commands
    def Speak(self, audio):
        engine = pyttsx3.init('sapi5')
        voices = engine.getProperty('voices')
        engine.setProperty('voice', voices[1].id)
        engine.say(audio)
        engine.runAndWait()
     
    # Method to take input voice commands
    def takeCommand(self):
 
        # This method is for taking
        # the commands and recognizing the command
 
        r = sr.Recognizer()
        # from the speech_Recognition module
        # we will use the recongizer method
        # for recognizing
 
        with sr.Microphone() as source:
            # from the speech_Recognition module
            # we will use the Microphone module for
            # listening the command
 
            print('Listening')
            # seconds of non-speaking audio
            # before a phrase is considered complete
            r.pause_threshold = 0.7
            audio = r.listen(source)
 
            try:
                print("Recognizing")
                Query = r.recognize_google(audio, language='en-in')
 
                # for listening the command
                # in indian english
                print("the query is printed='", Query, "'")
 
                # for printing the query or the
                # command that we give
            except Exception as e:
 
                # this method is for handling
                # the exception and so that
                # assistant can ask for telling
                # again the command
                print(e) 
                
                print("Say that again sir")
                return "None"
            return Query
 
    # Method to restart PC
    def restart(self):
        self.Speak("do u want to switch off the computer sir")
        take = self.takeCommand()
        choice = take
        if choice == 'yes':
            print("Shutting down the computer")
            os.system("shutdown /s /t 30")
            self.Speak("Shutting the computer")
        if choice == 'no':
            print("Thank u sir")
            self.Speak("Thank u sir")
