Segmentation fault: 11エラー Pythonで音声認識 お助けください

Question

前提・実現したいこと

Pythonでこま切れに音声認識をしたいです。
一番下のfor文を１周はできますが２周目の録音開始直前にエラーが出ます。

発生している問題・エラーメッセージ

Answer 1

ループ内で、audio.terminate()を呼ばないようにするか、
openの直前にaudio = pyaudio.PyAudio()を持ってきてはいかがですか？

[cl_]

openの直前に
audio = pyaudio.Pyaudio()
持ってきたら上手くいきました、最高です。
