从 Python 中的麦克风录制音频

Question

我正在尝试在 python 中创建一个虚拟助手，它使用语音识别。 虽然在运行程序时，它没有接受任何语音输入，尽管没有错误。 我的麦克风连接正确，我很确定代码有问题。 请帮我解决一下这个。

        #assistant responds back using audio and text from response

我认为问题在于唤醒词应该降低（Python区分大小写）

顺便说一句，看看我的虚拟助手 Ida

# A function for wake word
def wakeWord(text):
    WAKE_WORDS = {'Hey Jarvis', 'Jarvis', 'Hello Jarvis', 'I need help'} #list of wake words

    text = text.lower() #convert the text to lower case words

    #Check to see if user input is a wake word
    for phrase in WAKE_WORDS:
        if phrase.lower() in text: #convert the phrase to lower case words as well
            return True
        else: return False
