A general overview of the AdApt project and the research that is performed within the project is presented. In this project various aspects of human-computer interaction in a multimodal conversational dialogue systems are investigated. The project will also include studies on the integration of user/system/dialogue dependent speech recognition and(More)
This paper presents an overview of methods that can be used to collect and analyse data on user responses to spoken dialogue system components intended to increase human-likeness, and to evaluate how well the components succeed in reaching that goal. Wizard-of-Oz variations, human–human data manipulation, and micro-domains are discussed in this context, as(More)
The study reported in this paper is based on results from a Swedish database of spontaneous computer-directed speech. This database was investigated to determine how people adapt their language when they interact with computers. A spoken dialogue system with an animated agent, August, was installed in a public location in downtown Stockholm. Members of the(More)
This paper presents the NICE fairy-tale game system, which enables adults and children to engage in conversation with animated characters in a 3D world. In this paper we argue that spoken dialogue technology have the potential to greatly enrichen the user's experience in future computer games. We also present some requirements that have to be fulfilled to(More)
Spoken language systems are highly complex and teaching of students in this subject matter and in the underlying technologies could benefit greatly from instructional software. The aim of this work has been to give students hands-on experience via a fully functioning spoken dialogue system as a teaching aid. This dialogue system was built using our toolkit(More)
This paper examines feedback strategies in a Swedish corpus of multimodal human–computer interaction. The aim of the study is to investigate how users provide positive and negative feedback to a dialogue system and to discuss the function of these utterances in the dialogues. User feedback in the AdApt corpus was labeled and analyzed, and its distribution(More)
This paper describes an empirical study of children's spontaneous interactions with an animated character in a speech-enabled computer game. More specifically, it deals with convergence of referring expressions. 49 children were invited to play the game, which was initiated by a collaborative " put-that-there " task. In order to solve this task, the(More)
This paper describes the Swedish spoken dialogue system August. This system has been used to collect spontaneous speech data, largely from people with no previous experience of speech technology or computers. The aim was to be able to analyse how novice users interact with a multi-modal information kiosk, placed without supervision in a public location. The(More)
