Chapter
This paper presents our ongoing work on the development of a multimodal dialogue system to enable user control of home appliances in an ambient intelligence environment. The physical interaction with the appliances is carried out by means of Octopus, a system developed in a previous study to ease communication with hardware devices by abstracting t...

Mayordomo is a multimodal dialogue system developed to ease user interaction with home appliances using speech and a GUI interface. Octopus is an operating system designed to provide ubiquitous access to computing resources using the Internet as the interconnection means. In this paper we describe the main characteristics of both systems as well as...
Article
Multimodal systems have attained increased attention in recent years, which has made possible important improvements in the technologies for recognition, processing, and generation of multimodal information. However, there are still many issues related to multimodality which are not clear, for example, the principles that make it possible to resemb...
Chapter
In this paper we propose a method for merging intentional and emotional information in spoken dialogue systems in order to make dialogue managers more efficient and adaptive. The prediction of the user intention and emotion is carried out for each user turn in the dialogue by means of a module conceived as an intermediate phase between natural lang...
Article
In this chapter, we revisit the main theories of human emotion and personality and their implications for the development of affective conversational agents. We focus on the role that emotion plays for adapting the agents' behaviour and how this emotional responsivity can be conveniently modified by rendering a consistent artificial personality. Th...
Chapter
This paper presents a new toolkit for the evaluation of spoken dialogue systems in Ambient Intelligence domains. It describes the design and implementation of the toolkit, which consists in several tools that can be employed to process corpora of recorded spoken interaction and automatically obtain statistical measures in order to assess and improv...
Chapter
Continuous advances in the field of spoken dialogue systems make the processe of design, implementation and evaluation of these systems more and more com-s plex. To solve problems emerging from this complexity, a technique which has attracted increasing interest during the last decades is based on the automatic generation of dialogues between the s...

Resumen: El desarrollo de la denominada Web 2.0 ha hecho posible la introducción de numerosas aplicaciones que han originado nuevas formas y canales de comunicación. Con la evolución de estas tecnologías, se han producido durante lá ultima década enormes avances en el desarrollo de mundos virtuales. En este artículo presentamos un caso específico d...
Conference Paper
This paper presents a multimodal dialogue system called Mayordomo which aims at easing the interaction with home appliances using speech and a graphical interface within an Ambient Intelligence environment. We present the methods employed for implementing the system describing the design of the user-system interactions as well as additional featur...
Conference Paper
In this paper, we present a technique for learning new dialog strategies by using a statistical dialog manager that is trained from a dialog corpus. A dialog simulation technique has been developed to acquire data required to train the dialog model and then explore new dialog strategies. A set of measures has also been defined to evaluate the dialo...
Conference Paper
This paper proposes a new technique to increase the robustness of spoken dialogue systems employing an automatic procedure that aims to correct frames incorrectly generated by the system’s component that deals with spoken language understanding. To do this the technique carries out a training that takes into account knowledge of previous system mis...
Article
Full-text available
In this paper we present a new technique to enhance the performance of spoken dialogue system, which employs contextual models and grammatical rules to optimise the automatic correction of some errors made by the ASR component of these systems. Different experiments have been carried out to evaluate this technique employing a previously developed s...
Article
Full-text available
This paper presents our current work in locating users through RFID devices for a multimodal dialogue system called Mayordomo. The paper explains how RFID works and describes the system architecture to connect hardware devices (RFID) and software applications (Mayordomo). Finally several examples are shown to explain how this implementation improve...
