We present an implemented concept-to-speech (CTS) syst@n'~J tl~at offers original proposals for certain couplings-oi r dialogue computation with prosodic computation. Specifically, the semantic interpretation, task modeling and dialogue strategy modules in a working spoken dialogue system are used to generate prosodic features to better convey the meaning of system replies. The new CTS system e...

The purpose of this study was to investigate the degree of customer orientation in a small sample of Swedish SME's. In-depth interviews were carried out with product developers in four companies from three different product areas. The questions posed concerned the company's overall strategy, ways of managing the external dialogue (i.e. the dialogue between the company and the customer), and way...

Given the state of the art of current language and speech technology, errors are unavoidable in present-day spoken dialogue systems. Therefore, one of the main concerns in dialogue design is how to decide whether or not the system has understood the user correctly. In human-human communication, dialogue participants are continuously sending and receiving signals on the status of the information...

We implemented a spoken dialogue system architecture for rapid prototyping. The features that support rapid prototyping include a clear separation of generic dialogue processing algorithms from domain and language speci c knowledge sources. In an experiment, it could be shown that six individuals could specify these domain and language speci c knowledge sources within 8 to 12 hours to come up w...

The use of dialogue systems in vehicles raises the problem of making sure that the dialogue does not distract the driver from the primary task of driving. Earlier studies have indicated that humans are very apt at adapting the dialogue to the traffic situation and the cognitive load of the driver. The goal of this paper is to investigate strategies for interrupting and resuming in, as well as c...

Formal argumentation based dialogue models have attracted some research interests recently. Within this line of research, we propose a formal model for argumentation-based dialogues between agents, using assumption-based argumentation (ABA). Thus, the dialogues amount to conducting an argumentation process in ABA. The model is given in terms of ABA-specific utterances, debate trees and forests ...

With maturing speech technology, spoken dialogue systems are increasingly moving from research prototypes to fielded systems. The fielded systems however generally employ much simpler linguistic and dialogue processing strategies than the research prototypes. We describe an implemented spoken-language dialogue system for a travel planning domain which supports a mixed initiative dialogue strate...

We undertook a case study in order to explore deliberative dialogue as a system-level knowledge translation and exchange (KTE) strategy and to describe the design features and intended effects of this dialogue. Our data included observations made during the dialogue, evaluations completed by dialogue participants and interviews. We placed these data in the context of our broader experience. We ...

My PhD focusses on argumentation-based communication between agents. I take, as a starting point, the argumentation system proposed by Garcı́a and Simari [22], which allows a single agent to reason about its beliefs. I define a novel dialogue system that allows two agents to use Garcı́a and Simari’s system to carry out inter-agent argumentation. I define two specific protocols for two different t...
