Towards Incremental Speech Generation in Dialogue Systems

Gabriel Skantze, Anna Hjalmarsson
2010 SIGDIAL Conferences  
We present a first step towards a model of speech generation for incremental dialogue systems.  ...  The model allows a dialogue system to incrementally interpret spoken input, while simultaneously planning, realising and selfmonitoring the system response.  ...  But, as we will see, the output in an incremental system must also be flexible, as speech plans are incrementally produced and amended.  ...

Role Play Dialogue Aware Language Models Based on Conditional Hierarchical Recurrent Encoder-Decoder

Ryo Masumura, Tomohiro Tanaka, Atsushi Ando, Hirokazu Masataki, Yushi Aono
2018 Interspeech 2018  
Our motivation is to improve automatic speech recognition (ASR) performance in role play dialogues such as contact center dialogues and service center dialogues.  ...  We propose role play dialogue-aware language models (RPDA-LMs) that can leverage interactive contexts in role play multiturn dialogues for estimating the generative probability of words.  ...  In real ASR applications, more flexible LMs are required because two speaker's utterances rarely alternate.  ...

Audiovisual interface for Czech spoken dialogue system

Pavel Ircing, Jan Romportl, Zdenek Loose
The interface was originally designed for the dialogue system that allows elderly users to reminiscence about their photographs.  ...  However, the modular architecture of the whole system and the flexibility of messages that are used for communication between the modules facilitate seamless transition of the application to any domain  ...  It is basically a system comprising a central messaging hub and flexible mechanisms for information flow control.  ...

Information density and overlap in spoken dialogue

modules in spoken and incremental dialogue systems.  ...  Incremental dialogue systems are often perceived as more responsive and natural because they are able to address phenomena of turn-taking and overlapping speech, such as backchannels or barge-ins.  ...  Thanks to Michael White for making the initial suggestion to explore information density in dialogue and to Chika Ugwuanyi for her help in setting up the website for experimentation. 28  ...

Robust Processing of Situated Spoken Dialogue [chapter]

Pierre Lison, Geert-Jan M. Kruijff
2009 Lecture Notes in Computer Science  
We present an integrated approach for addressing these two issues, based on a robust incremental parser.  ...  The approach is fully implemented in a dialogue system for autonomous robots.  ...  Conclusions We presented an integrated approach to the processing of (situated) spoken dialogue, suited to the specific needs and challenges encountered in human-robot interaction.  ...

A Temporal Simulator for Developing Turn-Taking Methods for Spoken Dialogue Systems

Ethan Selfridge, Peter A. Heeman
2012 SIGDIAL Conferences  
Developing sophisticated turn-taking behavior is necessary for next-generation dialogue systems.  ...  As a foundation for advancing turn-taking behavior, we present a temporal simulator that models the interaction between the user and the system, including speech, voice activity detection, and incremental  ...  Acknowledgments We thank to the reviewers for their thoughtful suggestions and critique. We acknowledge funding from the NSF under grant IIS-0713698.  ...

Enabling robust and fluid spoken dialogue with cognitively impaired users

Ramin Yaghoubzadeh, Stefan Kopp
2017 Proceedings of the 18th Annual SIGdial Meeting on Discourse and Dialogue  
This hybrid DM architecture affords incremental processing of uncertain input, a flexible, mixed-initiative information grounding process that can be adapted to users' cognitive capacities and interactive  ...  We present the flexdiam dialogue management architecture, which was developed in a series of projects dedicated to tailoring spoken interaction to the needs of users with cognitive impairments in an everyday  ...  NLU performed heuristic extraction of best guesses for this slot from ASR hypotheses.  ...

Supporting Spoken Assistant Systems with a Graphical User Interface that Signals Incremental Understanding and Prediction State

Casey Kennington, David Schlangen
2016 Proceedings of the 17th Annual Meeting of the Special Interest Group on Discourse and Dialogue  
We explore the use of a graphical output modality for signalling incremental understanding and prediction state of the dialogue system.  ...  By visualising the current dialogue state and possible continuations of it as a simple tree, and allowing interaction with that visualisation (e.g., for confirmations or corrections), the system provides  ...  Thanks also to Julian Hough for helping with experiments.  ...

Evaluation and Optimisation of Incremental Processors

Timo Baumann, David Schlangen
2011 Dialogue and Discourse  
We believe that this work will help enable principled comparison of components for incremental dialogue systems and portability of results.  ...  Incremental spoken dialogue systems, which process user input as it unfolds, pose additional engineering challenges compared to more standard non-incremental systems: Their processing components must be  ...  We wish to thank the anonymous reviewers for their very helpful comments.  ...

It's About Time: Turn-Entry Timing For Situated Human-Robot Dialogue

Felix Gervits, Ravenna Thielstrom, Antonio Roque, Matthias Scheutz
2020 SIGDIAL Conferences  
Turn-entry timing is an important requirement for conversation, and one that few spoken dialogue systems consider.  ...  Our approach involves incremental processing and lexical prediction of the turn in progress, which allows a situated dialogue agent to start its turn and initiate actions earlier than would otherwise be  ...  We are especially grateful to Brad Oosterveld, Evan Krause, and Zach Munro for their technical assistance.  ...

Optimising Incremental Dialogue Decisions Using Information Density for Interactive Systems

Nina Dethlefs, Helen Wright Hastie, Verena Rieser, Oliver Lemon
2012 Conference on Empirical Methods in Natural Language Processing  
Unfortunately, prior work has focused largely on deterministic incremental decision making, rendering system behaviour less flexible and adaptive than is desirable.  ...  Incremental processing allows system designers to address several discourse phenomena that have previously been somewhat neglected in interactive systems, such as backchannels or barge-ins, but that can  ...  A Reward Function for Incremental Dialogue Based on Information Density To train the HRL agent, we use a partially datadriven reward function.  ...

A Multimodal In-Car Dialogue System That Tracks The Driver's Attention

Spyros Kousidis, Casey Kennington, Timo Baumann, Hendrik Buschmeier, Stefan Kopp, David Schlangen
2014 Proceedings of the 16th International Conference on Multimodal Interaction - ICMI '14  
In-car dialogue systems ignore these important aspects, making them more distracting than even cell-phone conversations.  ...  We developed and tested a "situationally-aware" dialogue system that can interrupt its speech when a situation which requires more attention from the driver is detected, and can resume when driving conditions  ...  The authors would like to thank Oliver Eickmeyer and Michael Bartholdt for helping implement the system setup, as well as Gerdis Anderson and Fabian Wohlgemuth for assisting as experimenters.  ...
