| Outline of Final Research Achievements |
In order to understand speech of a user and act adequately, service robots need to have the pre-designed linguistic knowledge, such as lexicon, grammar and the relationship between the meaning of speech and actions of robots. However, the robot cannot adequately act when a user uttered the term that is not included in the pre-designed knowledge. To solve this problem, in this research, we developed the method to extend the linguistic knowledge by statistically analyzing phoneme sequences of the new wordings. On the other hand, utterances for navigation often includes relative spatial concepts. However, reference objects which are required to understanding relative spatial concepts may not be included in the utterances. In this research, we proposed a method for learning relative spatial concepts while estimating the reference objects. In this method, a robot extracts candidates of reference object from an occupancy grid map.
