Question

我正试图从这里测试个人助理：https://pythonspot.com/en/personal-assistant-jarvis-in-python/

我确信我已经安装了所有模块和库等（花了20分钟来设置！）

问题在于，当我运行它时，它会说＆＃34;嗨弗兰克什么能为你做什么？＆＃34;但后来它抛出了这个错误：

/usr/bin/python3.5 /home/me/PycharmProjects/PersonalAssistant/PersonalAssistant.py

        location = data[2]
        speak("Hold on Frank, I will show you where " + location + " is.")

    jarvis(data)

Answer 1

此代码：

with sr.Microphone() as source:
    print("Say something!")
audio = r.listen(source)

应该是

with sr.Microphone() as source:
    print("Say something!")
    audio = r.listen(source)

请注意缩进以及示例here。当麦克风发生故障时，不会使用适当的缩进执行侦听代码。

你的下一个问题是麦克风失败，这是一个pyaudio问题，你需要正确配置音响系统，详见PyAudio prints ALSA warnings and does not work

由于该计划没有找到我所说的，问题是什么，因此在语音登记计划方面存在问题？
