python - 语音识别，断言错误 "Source must be an audio source"

Question

这是我的代码:

import speech_recognition as sr

r = sr.Recognizer()

with sr.Microphone() as source:
    print('Say Something')
    audio = r.listen(source)
    voice_data = r.record(audio)
    print(voice_data)

当我在终端上输入“python main.py”并启动程序时，它开始监听但没有听懂我说的话。我试过使用 adjust_for_ambient_noise()而不是 listen()但它也没有改变任何东西。

我使用的是 macOS Catalina 和 Python 3.8.1。

这是我得到的错误:

Traceback (most recent call last):
  File "main.py", line 8, in <module>
    voice_data = r.record(audio)
  File "/Users/sefailyasoz/PycharmProjects/SpeechAssistant/venv/lib/python3.8/site-packages/speech_recognition/__init__.py", line 483, in record
    assert isinstance(source, AudioSource), "Source must be an audio source"
AssertionError: Source must be an audio source 

这是我使用 adjust_for_ambient_noise() 时得到的结果，如果我使用 listen ，它并没有结束，它只是在听，我以 Ctrl+C 结束它。

好吧，我稍微改变了我的功能

def record_audio(ask=False):
    with sr.Microphone() as source:
        if ask:
            turkishSiri_speak(ask)
        audio = r.listen(source)
        voice_data = ''
        try:
            voice_data = r.recognize_google(audio , language='tr-TR')
        except sr.UnknownValueError:
            turkishSiri_speak('Ne söylediğini anlayamadım')
        except sr.RequestError:
            turkishSiri_speak('Google konuşma servisinde bir problem var')
        return voice_data

但最大的问题是 macOS 问题，我必须允许 pycharm 或 Visual Studio 代码使用我的麦克风。在更改功能之前，它已经在授予权限后工作
