import SpeechRecognition as sp
def takeCommand():
r = sp.Recognizer()
with sp.Microphone() as source:
print("Listening....")
r.pause_threshold = 1
audio = r.listen(source)
try:
print("Recognising...")
query = r.recognize_google(audio,language="en-in")
print(query)
except Exception as e:
print(e)
speak("say that again please")
return None
return query
takeCommand()'''这是返回错误，如

python3: src/hostapi/alsa/pa_linux_alsa.c:3641: PaAlsaStreamComponent_BeginPolling: Assertion `ret == self->nfds' failed.我安装了适当的库，也试着理解像pyaudio之类的东西来摆脱这个问题，昨天我遇到了和pysttx3一样的事情，但通过重启笔记本电脑解决了这个问题，但这不起作用。

您的代码应如下所示：
import speechRecognition as sr
def takeCommand():
r = sr.Recognizer()
with sr.Microphone() as source:
print("Listening...")
r.pause_threshold = 1
audio = r.listen(source)
try:
print("Recognizing...")
query = r.recognize_google(audio, language='en-in') #Using google for voice recognition.
print(f"User said: {query}\n") #User query will be printed.
except Exception as e:
# print(e)
print("Say that again please...") #Say that again will be printed in case of improper voice
return "None" #None string will be returned
return query首先，通过在终端中输入以下命令来导入库-
pip install speechRecognition
