Question

我对Python比较陌生。我正在尝试创建一个程序来打开YouTube。在这里，用户应该说“ open youtube”，而python应该在浏览器中将其打开。但是，我在以下代码中不断收到操作系统错误。当我在朋友的PC上尝试相同的程序时，错误出乎意料地消失了！但是由于某种原因它仍然存在于我的系统中。经过深入研究，我发现问题出在“ audio = r.listen（source）”行，其中代码返回错误。请帮助。（我已经检查了麦克风，似乎没有问题。）

import pyttsx3 #pip install pyttsx3
import speech_recognition as sr #pip install speechRecognition
import webbrowser
import os

engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
# print(voices[1].id)
engine.setProperty('voice', voices[0].id)


def takeCommand():
    #It takes microphone input from the user and returns string output

    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        r.pause_threshold = 0.5
        audio = r.listen(source)

    try:
        print("Recognizing...")    
        query = r.recognize_google(audio, language='en-in')
        print(f"User said: {query}\n")

    except Exception as e:
        # print(e)    
        print("Say that again please...")  
        return "None"
    return query


while True:
    query = takeCommand().lower()

if 'open youtube' in query:
            webbrowser.open("youtube.com") #end of code


I am getting the following error message:
