We are investigating prosodic and linguistic features of social interaction, such as turn taking, backchannels, and exchange structures, through statistical analysis of large-scaled spoken dialogue corpora. By doing this, we are trying to find out linguistic/psychological constraints on human language use in daily situations.

We are investigating prosodic and linguistic features of speech disfluencies, such as fillers, repetitions, and repairs, through statistical analysis of large-scaled spoken dialogue corpora. By doing this, we are trying to develp a psycholinguistic model of speech production and to find their role in communication.

We are investigating the roles of prosody, i.e., pitch, speech rate, etc., in the communication of dialogue acts and discourse structures, through statistical analysis of large-scaled spoken dialogue corpora.

We are investigating human sentence comprehension mechanism using both computational and psycholinguistic approaches, aiming at developing a computational model which is consistent with psycholinguistic facts on human sentence processing, e.g., garden path phenomena. Psychological experiments are being conducted in corporation with a researcher at Osaka University.

The research aims at developing a natural language dialogue system which communicates with a human in order to cooperatively solve a given task. In this connection, we are conducting a series of competitions, DiaLeague, for objectively evaluating the total performance of natural language dialogue systems. The competitions are designed so that a system with flexible communication ability to talk with unlimited partners on the Web gains a high score. The goal of developing such a system is to realize robust communication with humans in unrestricted situations.
