Toward enhancement of human communication abilities, the AHC Laboratory is promoting the research and education on a wide variety of technologies that support communications
between human-to-human and human-to-computer, including multilingual incremental speech-to-speech translation, dialog systems, speech and emotion recognition/synthesis,
and brain analysis related human communication. High priority is placed not only to the theoretical aspect but also the technical applicability, including the practical application of
a prototype system. In this talk we also introduce our latest activities at NAIST AHC laboratory.
Dialogue systems have been developed to fulfill users’ demands as a considerate secretary by using defined frames that describe knowledges
to help humans, especially as task-oriented dialogue systems. However, it is difficult for existing dialogue systems to respond to users’ queries
that are beyond the descriptive capacities of frames, because such frames are defined by considering possible action space of the system.
On the other hand, keyword search or question answering systems covers the limitation of the frame-based system, however, it is difficult
for these systems to behave as the frame-based system. Toward the system that can go beyond these limitations, we focus on predicate-argument structure (PAS),
a semantic representation, to make the system possible to cooperate with users in tasks of information navigation and attentive listening.
The system is able not only to capture the intention of the user by using the semantic representation but also to cooperate with users.
The system dynamically extends their knowledge, which is represented in PAS, by integrating their original knowledge and extracted knowledge
through a dialogue, to realize the intellectual cooperative dialogue.

He received his B.S. from Kyoto Institute of Technology in 1981 and Ph.D. from Kyoto University in 1992. He was Associate Professor of Graduate School of Information Science at Nara Institute of Science and Technology in 1994-2000. He was Director of ATR Spoken Language Communication Research Laboratories in 2000-2008 and Vice president of ATR in 2007-2008. He was Director General of Keihanna Research Laboratories and the Executive Director of Knowledge Creating Communication Research Center, National Institute of Information and Communications Technology, Japan in 2009-2010. He is currently Director of Augmented Human Communication laboratory and a full professor of Graduate School of Information Science at Nara Institute of Science and Technology. He is interested in modeling and systems of speech-to-speech translation and speech recognition. He is one of the leaders of speech-to-speech translation research and has been serving for various speech-to-speech translation research projects in the world including C-STAR, IWSLT and A-STAR. He was a project leader of the world first network-based commercial speech-to-speech translation service for 3-G mobile phones in 2007 and VoiceTra project for iPhone in 2010. From 2014 he is also coordinating NAIST Big Data Project with all
