 note = {In order to address a learning effect of the Spoken Dialogue System (SDS), we carried out field experiments using SDS of music retrieval for long periods and analyzed sequential shifts of the system performance and the users’ utterances. Experimental results revealed that the user of SDS changed the strategy of dialogue with the system during the learning process. Analysis of the questionnaire suggested that the user changed the evaluation of SDS according to the learning experience. The leaning effect of SDS is known a priori, however, our results displayed a new form of the learning effect. We discussed that it may be taken into consideration to evaluate SDS users as well as the system.},
