我的代码:

import pyttsx3
import speech_recognition as sr
import datetime
import wikipedia
import webbrowser
import os
import smtplib
import jdatetime
import persian

Boss = 'Mohamaad'
print('Hello sir %s' % Boss)
engine = pyttsx3.init('sapi5')
voices = engine.getProperty('voices')
engine.setProperty('voice',voices[0].id)

def speak(text):
    engine.say(text)
    engine.runAndWait()

speak('Hello sir %s' % Boss)

def takeCommand():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        r.record(source,duration=2)
        speak('I am Listening sir')
        print("Listening ....")
        audio = r.listen(source)

    try :
         print("Recognizing...")
         query = r.recognize_google(audio, Language ='en-us')
         print(f"user said: {query}\n")

    except Exception as e:
        print("Say that again please")
        speak('Say that again please')
        query=None

    return query

wishMe()
query = takeCommand()



#Logic for executing tasks as per the query
if 'wikipedia' in query.lower():
    speak('searching in wikipedia....')
    query = query.replace("wikipedia", "")
    results = wikipedia.summary(query, sentences =2)
    print(results)
    speak(results)

elif 'open youtube' in query.lower():
    url = 'youtube.com'
    chrome_path = 'C:\Program Files (x86)\Google\Chrome\Application/chrome.exe %s'
    webbrowser.get(chrome_path).open(url)
elif 'open Google' in query.lower():
    url = 'Google.com'
    chrome_path = 'C:\Program Files (x86)\Google\Chrome\Application/chrome.exe %'
    webbrowser.get(chrome_path).open(url)
elif 'open github' in query.lower():
    url = 'github.com'
    chrome_path = 'C:\Program Files (x86)\Google\Chrome\Application/chrome.exe %'
    webbrowser.get(chrome_path).open(url)
elif 'Play music' in query.lower():
    songs_dir = "C:\\Users\\mohmmad\\Downloads\\Music"
    songs = os.listdir(songs_dir)
    speak(songs)
    os.startfile(os.path.join(songs_dir,songs[0]))

elif 'time' in query():
    strTime = datetime.datetime.now().strftime("%H:%M:%S")
    speak(f"{Boss} the time is {strTime}")

输出:

感谢您的帮助

推荐答案

您需要检查查询是否不是无

You need to check if the query is not None

if query:
    if 'wikipedia' in query.lower():
        speak('searching in wikipedia....')
        query = query.replace("wikipedia", "")
        results = wikipedia.summary(query, sentences =2)
        print(results)
        speak(results)

    elif 'open youtube' in query.lower():
        url = 'youtube.com'
        chrome_path = 'C:\Program Files (x86)\Google\Chrome\Application/chrome.exe %s'
        webbrowser.get(chrome_path).open(url)

标头中的错误是因为您尝试 lower()无类型对象，并且从您的代码看来，它已在查询值中发生.

The error that in the header is because you are trying to lower() None type object and from your code it seems that it's happened in the query value.
