NTT CorporationNTT CorporationNTT CorporationNTT CorporationNTT Data CorporationNTT Data CorporationNTT CorporationLREC 2018 Special Speech Sessions "Speech Resources Collection in Real-World Situations"; Phoenix Seagaia Conference Center, Miyazaki; 2018-05-09This paper introduces the dialogue systems (chat-oriented and argumentative dialogue systems) we have been developing at NTT together with the speech and language resources we used for building them. We also describe our field trials for deploying dialogue systems on actual premises, i.e., shops and banks. We found that the primary problem with dialogue systems is timing, which led to our current focus on multi-modal processing. We describe our multi-modal corpus as well as our recent research on multi-modal processing
