线程没有执行类功能

Question

我试图通过线程调用hear（）并在调用stop（）时杀死它。可以看出，start（）工作正常，但是线程似乎并没有调用听觉（）。我要去哪里？提前致谢 ：）

import speech_recognition as sr
from threading import Thread
import time

class SpeechRecognizer():
    HEAR = True
    speech_recognizer = sr.Recognizer()
    
    def __init__(self,src_lang='hi-IN'):
        self.src_lang=src_lang
        self.hearing_thread = Thread(target=self.hear)

    def hear(self):
        print('in hearing')
        with sr.Microphone() as source:
            self.speech_recognizer.adjust_for_ambient_noise(source)
            while self.HEAR:
                audio = self.speech_recognizer.listen(source)
                text = self.speech_recognizer.recognize_google(audio, language=self.src_lang)
                print(text)

    def start(self):
        print('starting to hear')
        self.hearing_thread.start()


    def stop(self):
        self.HEAR = False
        self.hearing_thread.join()
        print('done hearing')

if __name__=='__main__':
    sr=SpeechRecognizer()
    sr.start()
    for i in range(5):
        time.sleep(1)
    sr.stop()

事实证明，存在命名冲突。 segress_rcognition软件包和类实例都命名为相同。当我将类实例从SR重命名为其他名称时，它开始工作正常。
