This paper describes work on dialogue data collection and dialogue
system design for personal assistant humanoid robots undertaken
at eNTERFACE 2016. The emphasis has been on the system's speech capabilities
and dialogue modeling of what we call LifeLine Dialogues, i.e.
dialogues that help people tell stories about their lives. The main goal
behind this type of application is to help elderly people exercise their
speech and memory capabilities. The system further aims at acquiring a
good level of knowledge about the person's interests and thus is expected
to feature open-domain conversations, presenting useful and interesting
information to the user. The novel contributions of this work are: (1) a

exible spoken dialogue system that extends the Ravenclaw-type agentbased
dialogue management model with topic management and multimodal
capabilities, especially with face recognition technologies, (2) a
collection of WOZ-data related to initial encounters and presentation
of information to the user, and (3) the establishment of a closer conversational
relationship with the user by utilizing additional data (e.g.
context, dialogue history, emotions, user goals, etc.).
