People like to be, or partly, encouraged
when their opinions or challenges are supported by
listeners, even the listeners are robots. Encouraging
responses from the robot which seem to get users' points
potentially improve users' feeling in human computer
dialog. According to this hypothesis, this paper proposes
a method to generate supporting responses to users'
opinions or challenges. The core ideas and contributions
of the proposed method are: (1) multiple search engines
cooperate, and (2) each engine random asks itself or ask
another one to obtain more related information from the
internet in multiple turns; then (3) final responses are
abstracted from the answers. We call these three steps as
Self-Talk. The comparisons between Self-Talk and
several commercial open speech assistants show that the
proposed method does generate suitable answers to
users when they present their opinions or challenges in
dialog. The hypothesis is positively evaluated that
encouraging responses could improve users' chat feeling.
