JARVIS语音助手的回溯错误

Question

我在做贾维斯的助理，但是我有这个错误

Traceback (most recent call last):
File "d:\project\Jarvis\jarvis.py", line 43, in <module>
query = takeCommand().lower()
AttributeError: 'NoneType' object has no attribute 'lower

而且我还安装了py音频，它正在工作。

我的代码在下面，请看一下

import pyttsx3
import datetime
import speech_recognition as sr
import pyaudio
import Wikipedia

engine = pyttsx3.init("sapi5")
voices = engine.getProperty("voices")
engine.setProperty("voice", voices[0].id)

def speak(audio):
    engine.setProperty("rate", 130)
    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 Jarvis sir! How may I help you")
def takeCommand():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        r.pause_threshold = 1
        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("Say that again please...")
         return "None"
         return query 

if __name__ == "__main__":
    wishMe()
    while True:
        query = takeCommand().lower()
        if 'wikipedia' in query:  
            speak('Searching Wikipedia...')
            query = query.replace("wikipedia", "")
            results = wikipedia.summary(query, sentences=2) 
            speak("According to Wikipedia")
            print(results)
            speak(results)

我想不出如何修正这个错误。我是用CodeWithHarry制作的youtube上的一个教程来做的

目前，takecommand()函数在识别音频时不返回任何内容。但是，您确实有一个返回语句(返回查询)，它看起来是在错误的位置，如果您将它移到除了行之前，它应该可以工作。所以这个函数应该如下所示：

def takeCommand():
    r = sr.Recognizer()
    with sr.Microphone() as source:
        print("Listening...")
        r.pause_threshold = 1
        audio = r.listen(source)
    try:
        print("Recognizing...")
        query = r.recognize_google(audio, language="en-in")
        print(f"User said: {query}\n")
        return query
    except Exception as e:
        print("Say that again please...")
        return "None"
