This paper describes Dico II+, an in-vehicle dialogue system demonstrating a novel combination of flexible multimodal menu-based dialogueand a “speech cursor” which enables menu navigation as well as browsing long list using haptic input and spoken output. | Multimodal Menu-based Dialogue with Speech Cursor in DICOII Staffan Larsson University of Gothenburg Sweden sl@ling.gu.se Alexander Berman Talkamatic AB Sweden alex@talkamatic.se Jessica Villing University of Gothenburg Sweden jessica@ling.gu.se Abstract This paper describes Dico II an in-vehicle dialogue system demonstrating a novel combination of flexible multimodal menu-based dialogueand a speech cursor which enables menu navigation as well as browsing long list using haptic input and spoken output. 1 Introduction Dico is a multimodal in-car dialogue system application originally developed in the DICO with capital letters project by Volvo Technology AB and the University of Gothenburg. Dico is built on top of the GoDiS dialogue system platform Larsson 2002 which in turn is implemented using TrindiKit Traum and Larsson 2003 . The main goal of the original Dico application Olsson and Villing 2005 Villing and Larsson 2006 was to develop an interface that is less distracting for the driver and thus both safer and easier to use than existing interfaces. Larsson and Villing 2009 described the Dico II system resulting from work in the DICO project. Since then the Dico demonstrator has been further developed. In this paper we describe the Dico II demonstrator which introduces a novel combination of flexible Multimodal Menu-Based Dialogue and a Speech Cursor which together enable flexible multimodal interaction without the need for looking at the screen. In the following we will first argue for the usefulness of in-vehicle dialogue systems. We will then briefly present the GoDiS platform which Dico II is based on as well as some aspects of flexible dialogue enabled by the GoDiS dialogue manager. 92 2 In-vehicle dialogue systems Voice interaction is a very natural means of communication for humans and enabling spoken interaction with technologies may thus make it easier and less cognitively demanding for people to interact with machines. However this requires that the .
