这个错误是什么？这是一个数字助理

Question

这是我的代码：

import speech_recognition
import pyttsx3
from datetime import date, datetime

robot_ear = speech_recognition.Recognizer()
robot_mouth = pyttsx3.init()
robot_brain = ""

while True:
    with speech_recognition.Microphone() as mic:
        print("Robot: I'm Listening")
        audio = robot_ear.listen(mic)

    print("Robot:...")

    try:
        you = robot_ear.recognize_google(audio)
    except:
        you = ""
    print ("You: " + you)

    you = "hello"

    if you == "":
        robot_brain = "I can't hear you, try again!"
    elif"hello" in you:
        robot_brain = "Hello Huan"
    elif "today" in you:
        today = date.today()
        robot_brain = today.strftime("%B %d, %Y")
    elif "time" in you:
        now = datetime.now()
        robot_brain = now.strftime("%H hours %M minutes %S seconds")
    elif "president" in you:
        robot_brain = "Donald Trump"
    elif "bye" in you:
        robot_brain = "Bye Duong Gia Huan"
        print("Robot: " + robot_brain)
        robot_mouth.say(robot_brain)
        robot_mouth.runAndWait()
        break
    else:
        robot_brain = "I'm fine, Thank you, and you ?"

    print("Robot: " + robot_brain)
    robot_mouth.say(robot_brain)
    robot_mouth.runAndWait()

当我运行它时，出现这样的错误：

Robot: I'm Listening
Traceback (most recent call last):
  File "trolyao.py", line 12, in <module>
    audio = robot_ear.listen(mic)
  File "C:\Users\huana\AppData\Local\Programs\Python\Python38\lib\site-packages\speech_recognition\__init__.py", line 652, in listen
    buffer = source.stream.read(source.CHUNK)

    return pa.read_stream(self._stream, num_frames, exception_on_overflow)
OSError: [Errno -9999] Unanticipated host error

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "trolyao.py", line 12, in <module>
    audio = robot_ear.listen(mic)
  File "C:\Users\huana\AppData\Local\Programs\Python\Python38\lib\site-packages\speech_recognition\__init__.py", line 151, in __exit__
    self.stream.close()

    if not self.pyaudio_stream.is_stopped():
  File "C:\Users\huana\AppData\Local\Programs\Python\Python38\lib\site-packages\pyaudio.py", line 543, in is_stopped
    return pa.is_stream_stopped(self._stream)

帮我解决这个问题！！！我是Python的初学者！ 请帮我解决它

你能帮我吗？ 我不知道那是什么？ 我认为我们应该用麦克风修复音频，对吧？ Python 编程语言简介。 Python 由 Guido van Rossum 开发。 Guido van Rossum 于 1989 年开始实现 Python。Python 是一种非常简单的编程语言，因此即使您是编程新手，也可以轻松学习 Python。

Answer 1

r = sr.Recognizer()
with sr.Microphone() as source:
    r.pause_threshold = 1
    r.adjust_for_ambient_noise(source, duration=1)
    audio = r.listen(source)
try:
    print("Recognizing...")
    query = r.recognize_google(audio, language='en-us')
except Exception as e:
    print("Say that again please...")
    return "None"
return query

我不知道错误背后的原因，但我认为你需要添加上面的代码。我猜它不能清楚地识别音频，所以尝试调整环境噪音。我希望它有帮助。我也是初学者。和平
