I want to do this program in raspberry pi, but I can not.
It says
File "dialogue_test.py",line 72, in
data = stream.read(chunk)
File "usr//lib/python2.7/dist-packages/pyaudio.py",line 60 in read
reaturn pa.read_ stream(self._stream, num_frames)
IOError: [Erro Input overflowed]-9981
What should I do? and where is problem?

このプログラムをラズベリーパイで実行しようとしたら以上のエラーが出ました

どうすればいいでしょうか？
