如果我使用现场麦克风，SpeechRecognition不会给出响应。
我已经成功地安装了SpeechRecognition库和PyAudio使用python3-m pip安装。。。我正在虚拟环境中使用Raspberry Pi Zero：Python 3.7.3pip 21.0.1
我正在使用Adafruit I2S MEMS麦克风突破，并能够使用成功录制
arecord -D plughw:1 -c1 -r 48000 -f S32_LE -t wav -V mono -v file.wav
当我将其保存在文件(file.wav(中并使用以下代码时，语音识别器会工作：
import speech_recognition as sr
r = sr.Recognizer()
with sr.AudioFile('file.wav') as source:
audio = r.record(source)
try:
print("You said: " + r.recognize_google(audio))
except sr.UnknowValueError:
print("Sorry, could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
但当我想用以下代码进行实时语音识别时：
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone(1) as source:
print("Say something!")
audio = r.listen(source)
try:
print("You said: " + r.recognize_google(audio))
except sr.UnknowValueError:
print("Sorry, could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
它给出以下输出，并不断地说："说点什么"，而不显示任何文字记录：

Say something!
当我在一段时间后按下^C时，因为什么都没有发生，添加了以下位：
^CTraceback (most recent call last):
File "srwm.py", line 6, in <module>
audio = r.listen(source)
File "/home/pi/.virtualenvs/pythonyt/lib/python3.7/site-packages/speech_recognition/__init__.py", line 620, in listen

如果需要更多信息，请告诉我。我希望有一个真正聪明的人可以帮助我，提前谢谢！
第一次回答后的新代码：
import speech_recognition as sr
r = sr.Recognizer()
with sr.Microphone(1) as source:
print("Say something!")
audio = r.listen(source)
data = ""
try:
data = r.recognize_google(audio)
print("You said: " + data)
except sr.UnknownValueError:
print("Sorry, could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
return data
给出返回在函数外部的错误。
我想问题出在将语音翻译成文本的部分。。。试试这个：
data = ""
try:
data = r.recognize_google(audio)
print("You said: " + data)
except sr.UnknownValueError:
print("Sorry, could not understand audio")
except sr.RequestError as e:
print("Could not request results from Google Speech Recognition service; {0}".format(e))
return data
我想这是整个可以工作的代码：
import speech_recognition as sr
def Recognize():
r = sr.Recognizer()
with sr.Microphone(1) as source:
print("Say something!")
audio = r.listen(source)
data = ""
try:
data = r.recognize_google(audio)
print("You said: " + data)
except Exception as e:
print("Sorry, could not understand audio")
print(e)
return data
if __name__=="__main__":
data = Recognize().lower()
print(data)
