こんにちは！今日もたくさん話そう
Traceback (most recent call last):
  File "dialogue_test.py", line 88, in <module>
    talk(talk_message, CARD, DEVICE)
NameError: name 'talk' is not defined

というふうにエラーになってしまします
どうやって解決できるでしょうか

詳細情報

このスクリプトに関係するAPIまたはアプリ

  • requests (PythonのHTTPライブラリ)
  • pyaudio (pythonでマイク入力)
  • AquesTalkPi (合成音声)
  • docomo雑談API (会話するためのAPI)
  • docomo音声認識API (音声を認識してTEXTに変換するAPI)*NTTじゃない方のやつ

環境

  • raspberry pi 2 model B
  • Python 2.7.9

参考サイト

スクリプトの出処（上のスクリプトは若干変えてます）

P.S.

APIKeyとレート（RATE)は正しく入力しているはずです

下の方からインデントを改善したほうがいいと言われますした
しかしインデントを正しく(サンプルコードに）合わせると

こんにちはー。海へ行きたいね

というようなエラーが出てきました
どうすればいいでしょうか？
