如何处理错误“ OSError：[Errno -9999]意外的主机错误”？

Question

我正在尝试编写代码以接受语音命令并相应地执行任务。但是，由于不断遇到错误：“ OSError：[Errno -9999] Unexpected to host error”，我陷入了困境。

我也检查了麦克风的可访问性，但事实并非如此。请帮助。

代码如下：

import pyttsx3 #pip install pyttsx3
import speech_recognition as sr #pip install speechRecognition
import datetime
import wikipedia #pip install wikipedia
import webbrowser
import os
import smtplib

engine = pyttsx3.init('sapi5')

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


def speak(audio):
    engine.say(audio)

    engine.runAndWait()



def wishMe():
    hour = int(datetime.datetime.now().hour)
    if hour>=0 and hour<12:
        speak("Good Morning!")

    elif hour>=12 and hour<18:
        speak("Good Afternoon!")   

    else:
        speak("Good Evening!")  

    speak("I am Alice. Please tell me how may I help you")       

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
