Abstract:
We have developed an educational environment for a modular spoken dialogue
system. The aim of the environment is to provide students, with different
backgrounds, means to understand the behaviour of spoken dialogue systems.
Focus in this paper is on dialogue and dialogue management. The dialogue
is recorded in a dialogue tree whose nodes are dialogue objects. The
dialogue objects model the constituents of the dialogue and consist
of parameters for modelling dialogue structure, focus structure and
a process description describing the actions of the dialogue system.
Various dialogue system behaviours can be achieved by modifying these
parameters. This is done using the educational environment, which is
interactive and facilitates examination, expansion and modification
of the dialogue object parameters and hence the system. The educational
system has been used in a number of courses at various universities
in Sweden.

Abstract:
In the EC funded research project REWARD professionals in the target
domain for a dialogue system were enabled to develop their own speech
driven telephone service (dialogue system). Specialists in speech recognition
technology provided them with graphical tools and technical advice.
Guided by their in-depth understanding of the target domain and target
user the four user partners developed four different dialogue systems.
The shift of focus in the dialogue system design process from technology
to end user driven design 'rationale' is influenced by research into
the design process of dialogue systems and provides valuable data that
informs user-centred-design processes of interactive systems. In this
paper we report on observations with regard to this end-user driven
design process. Dialogue features, which are a direct result of this
different approach to designing speech recognition applications, are
presented.

Abstract:
In some dialogue systems, the design of dialogue strategy is bound
tightly to the domain by straightforwardly hard-coding the response
actions into the system. Such a paradigm is quite easy to build up
a prototype system, but makes it difficult to port the system across
different domains. This paper presents a domain-transparent design
of dialogue management to increase system portability. The basic idea
of this framework is to extract the domain-dependent factors to form
an external domain knowledge database, leaving the dialogue management
component independent of the tasks. Based on the proposed framework,
porting to another domain needs only to replace the domain knowledge
database without changing the dialogue management module. This paper
also proposed a task description table interface enabling system developers
to design the dialogue strategy flexibly. With this approach, the effort
of porting a spoken dialogue system across different domains can be
relieved.

Abstract:
A human-machine dialogue system for the automation of call centre services
is presented, which features two novel functions: a. It integrates
spoken and written language processing through cooperation of a spoken
dialogue component and an OCR which extracts handwritten information
from application forms. b. It reads the forms and calls the applicants
(instead of being called by them) in order to collect the missing information
through a continuous speech, full sentence, machine-driven dialogue
which allows the user to formulate his answers at will. The system
has been developed for a Greek car insurance company in the framework
of the EU-project: LE-1 1802, ACCeSS, but can be easily adapted to
a different call centre application. The system is currently tested
at the company's premises.
