Abstract: This paper proposes to use dialogue systems to assess language learners' productive vocabulary. We introduce a new task where dialogue systems try to induce learners to use specific words during a natural conversation to assess their productive vocabulary. To investigate the feasibility of the dialogue systems that are capable of this task, we performed two kinds of experiments.
