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 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)
We present a novel scheme for enriching geographic database with street-level geographic information that could be useful for pedestrian navigation. A spoken dialogue system for crowdsourcing street-level geographic details was developed and tested in an in-lab experimentation. The system obtained 96.4% of concept values correctly after interacting with the(More)
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)
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)
Recently we have begun to build the basic tools for a generic speech-dialogue system, WAXHOLM. The main modules, their function and internal communication have been specified. The different components are connected through a computer network. A preliminary version of the system has been tested, using simplified versions of the modules. We will give a(More)
This paper presents the NICE fairy-tale game system, in which adults and children can interact with various animated characters in a 3D world. Computer games is an interesting application for spoken and multimodal dialogue systems. Moreover, for the development of future computer games, multimodal dialogue has the potential to greatly enrichen the user's(More)
