AttributeError: ChatBot对象没有属性“speech_to_text”

Question

我今天开始用Python编写代码，我试着遵循本教程(https://www.analyticsvidhya.com/blog/2021/10/complete-guide-to-build-your-ai-chatbot-with-nlp-in-python/) --您可以找到许多其他的博客，它们的代码完全相同。

import numpy as np
import speech_recognition as sr

# Beginning of the AI
class ChatBot():
    def __init__(self, name):
        print("----- starting up", name, "-----")
        self.name = name

def speech_to_text(self):
    recognizer = sr.Recognizer()
    with sr.Microphone() as mic:
         print("listening...")
         audio = recognizer.listen(mic)
    try:
         self.text = recognizer.recognize_google(audio)
         print("me --> ", self.text)
    except:
         print("me -->  ERROR")

然而，当尝试

if __name__ == "__main__":
     ai = ChatBot(name="Dev")
     while True:
         ai.speech_to_text()

将显示以下错误消息：

AttributeError: 'ChatBot' object has no attribute 'speech_to_text'

如果我用对象资源管理器检查ai，就没有'speec_to_text'，所以错误是有意义的。但是，我不知道如何解决这个问题。

如果我设置

ai.speech_to_text = speech_to_text(ai)

很管用，但在我看来是不对的。所有的网站都是这样做的，我不明白。

这是一个任天堂错误，实际上，您必须将speech_to_text函数放入该类中。像这样

class ChatBot():
    def __init__(self, name):
        print("----- starting up", name, "-----")
        self.name = name

    def speech_to_text(self):
        recognizer = sr.Recognizer()
        with sr.Microphone() as mic:
            print("listening...")
            audio = recognizer.listen(mic)
        try:
            self.text = recognizer.recognize_google(audio)
            print("me --> ", self.text)
        except:
            print("me -->  ERROR")
