Towards Closed Feedback Loops in HRI

Birte Carlmeyer, David Schlangen, Britta Wrede
2014 Proceedings of the 2014 Workshop on Multimodal, Multi-Party, Real-World Human-Robot Interaction - MMRWHRI '14  
In this paper, we present a first step towards incremental processing for modeling asynchronous human-robot interactions, to allow closed feedback loops in HRI.  ...  We achieve this by combining the incremental natural language processing framework InproTK with the human-robot dialog manager PaMini, which is based on generic interaction patterns.  ...  If the robot dialog act contains a verbalization output, a say task is sent via RSB and further processed by the incremental speech synthesis module (iSS) of InproTK.  ...

Revisiting Human-Agent Communication: The Importance of Joint Co-construction and Understanding Mental States

Stefan Kopp, Nicole Krämer

An Incremental Turn-Taking Model for Task-Oriented Dialog Systems

Andrei C. Coman, Koichiro Yoshino, Yukitoshi Murase, Satoshi Nakamura, Giuseppe Riccardi
2019 Interspeech 2019  
In this paper, we propose a token-by-token prediction of the dialog state from incremental transcriptions of the user utterance.  ...  To identify the point of maximal understanding in an ongoing utterance, we a) implement an incremental Dialog State Tracker which is updated on a token basis (iDST) b) re-label the Dialog State Tracking  ...  A turn-by-turn dialog state tracker estimates the dialog state p(st) only after processing all the tokens in the user's utterance.  ...

Incremental partition recombination for efficient tracking of multiple dialog states

Jason D. Williams
2010 2010 IEEE International Conference on Acoustics, Speech and Signal Processing  
To retain tractability, past work has suggested tracking dialog states in groups called partitions.  ...  For spoken dialog systems, tracking a distribution over multiple dialog states has been shown to add robustness to speech recognition errors.  ...  In practice there are too many dialog states to process in real time, so researchers have suggested maintaining a distribution over partitions of dialog states [3, 4] .  ...
