I don't have a strong preference here, but this could also be named as
SPEECH_RECOGNITION_ERROR_DENIED.. up to you to decide which is appropriate

I'd like to go with NOT_ALLOWED for now, but I don't feel strongly about it.

   // No speech heard before timeout.
   SPEECH_RECOGNITION_ERROR_NO_SPEECH,
   // Speech was heard, but could not be interpreted.
   SPEECH_RECOGNITION_ERROR_NO_MATCH,
   // There was an error in the speech recognition grammar.
   SPEECH_RECOGNITION_ERROR_BAD_GRAMMAR,
 };
