Conversation support system for people with language disorders — Making topic lists from Wikipedia

A conversation support system for people with language disorders is proposed. Although the existing conversation support system "Raku-raku Jiyu Kaiwa" (Easy Free Conversation) is effective, it has insufficient topic words and a rigid topic list structure. To solve these problems, this paper proposes a method that makes topic lists from Wikipedia's millions of topic words. Experiments using the proposed topic list showed that subject utterances increased and the variety of spoken topics was expanded.
