我正在我的树莓派 3b 上制作一个 gTTS 语音助手，比如 Siri。谷歌文本到语音的作品，但是当我使用 SpeechRecognition 和 Pyaudio 进行输入时，我得到了错误。我已经意识到我可以使这段代码更简单，它会做同样的事情，但我不需要改变它。这是代码：
import os
from gtts import gTTS
import time
import speech_recognition as sr
text_to_read = "Hello my name is Alex. What's your name? "
language = 'en'
slow_audio_speed = False
filename = '1.mp3'
filename2 = '2.mp3'
filename3 = '3.mp3'
filename4 = '4.mp3'
filename5 = '5.mp3'
filename6 = '6.mp3'
filename7 = '7.mp3'
filename8 = '8.mp3'
filename9 = '9.mp3'
filename10 = '10.mp3'
filename11 = '11.mp3'
filename12 = '12.mp3'
filename13 = '13.mp3'
def get_audio():
r = sr.Recognizer()
with sr.Microphone() as source:
audio = r.listen(source)
said = ""
try:
said = r.recognize_google(audio)
print(said)
except Exception as e:
print("Exception: " + str(e))
return said

audio_created13.save(filename13)

这是错误：

我正在使用 TKGOU UM6 USB 麦克风。你知道出了什么问题吗？
谢谢你。
