The Proceedings of the Department of Language and Speech of the University of Nijmegen
is an annual publication. One of its aims is to keep its readers informed about educational
and ongoing research activities at the department.
The Department of Language and Speech offers two full-time MA programmes:
- Language, Speech and Informatics is a four-year graduate programme. The major
emphasis of the programme is on language and speech technology, with a
substantial number of courses in computer science to support scientific research as
well as application development in that field. Courses in this programme cover
subjects such as phonetics, phonology, morphology, syntax and semantics, but also
principles of computer programming, the organisation of databases, and basic
courses in cognitive science. Apart from these basic courses there are more
specialised ones, for instance on signal analysis techniques and automatic speech
synthesis. In general, the programme aims at training highly-skilled professionals
who are qualified for employment in the office automation and information
industry, by providing a useful combination of courses in the field of linguistics,
speech science, computer science, and language and speech technology.
- Speech and Language Pathology is a three-year graduate programme which is
organisationally situated in the Department of Language and Speech. Several
faculties participate in this interdisciplinary programme: arts, social sciences and
medicine. The curriculum focuses on skills necessary to carry out both fundamental
and applied research in the field of pathological and normal language and speech
behaviour. The following courses are offered: speech production and perception,
psycholinguistics, neuropsychology, anatomy and physiology, instrumentation,
syntax, research methodology, speech and language pathology.
The department comprises three sections: Computer Linguistics, Corpus Linguistics and
Phonetics/Speech Technology. Thematically, the research topics pursued in these sections
are the following:
Funding for the research in the Department of Language and Speech comes from three
- computer linguistics:
- automatic syntactic and semantic analysis
- principle-based parsing
- natural language generation
- tools for second language acquisition
- corpus linguistics:
- corpus compilation
- corpus-related research into lexicology, syntax and discourse
- tools for the morpho-syntactic analysis of corpora and their subsequent exploitation
- phonetics and speech technology:
- automatic speech recognition
- text-to-speech conversion
- voice source modelling
- speaker recognition and speaker characteristics
- speech pathology
- Direct government funding': Research activities sponsored by the University of
Nijmegen, primarily in the framework of the research programme Language and
Speech Technology'. Some members of the department also participate in other
research programmes in the Faculty of Arts, viz. Language Theory and Language
Description' and Language in Social Context'. This funding category covers all
permanent staff plus part of the PhD students.
- Indirect government funding': Projects sponsored by the Netherlands Organization
for Scientific Research (NWO) and the Royal Dutch Academy of Sciences
- External funding': Funding provided by the Dutch Ministry of Education, the
Dutch Ministry of Economics, the EU, and research carried out under contracts with
In 1996, a PhD project started aiming at the development of a general purpose robust
parser based on descriptional data from the Algemene Nederlandse Spraakkunst' (the
project is carried out by drs. S. van Dreumel). Related to this project is the participation of
our department in the international Project Nederlandse Spraakkunst', funded by the
Dutch/Belgian Taalunie'. The major part of this project will be organized by the
Department of Dutch Language and Literature of the University of Nijmegen. From the
Department of Language and Speech, dr. P.A. Coppen will participate as one of the two
Also in 1996, a PhD project started at the Department of General Linguistics and
Dialectology aiming at the generation and analysis of natural language based on the
linguistic theory of Semantic Syntax. This project, carried out by drs. L. Teunissen, is
supervised by Prof. dr. P.A.M. Seuren and, for the Department of Language and Speech,
dr. P.A. Coppen.
A PhD thesis concerning a natural language interface to a database of chemical
experiments was defended in 1996 by dr. B. Van Bakel.
Dr. H. van den Heuvel has successfully defended his thesis on speaker specificity of
phonemes in January 1996. Drs. H. Kraayeveld's dissertation was completed in December.
This brought the relatively basic approach of speaker recognition research to its
completion. Work in this increasingly important field is continuing in the form of two new
projects, one project is funded by the Foundation for Technical Sciences (STW) while the
other project (CAVE), which is more application-oriented project, is funded under the EC
Telematics Application Programme. Both projects are seeing their first, extremely
Research in automatic speech recognition has progressed. The focus of the research of dr.
Helmer Strik has shifted somewhat, towards modelling of pronunciation variation.
Modelling of pronunciation variation will also be studied in two PhD projects that were
approved in 1996. Ir. J. Kessens started in December 1996, and will use a technical,
bottom-up approach. On the other hand, a more linguistic, top-down approach will be
pursued by drs. M. Wester, who started in January 1997.
Related to the research on pronunciation variation mentioned above is the research
carried out by dr. C. Cucchiarini within a three year research project that explores how
automatic speech recognition can be used in (partly) computerised tests of the
pronunciation quality of adults who learn Dutch as a second language. In this project we
collaborate with Cito (the Central Dutch Institute for Test Development), Swets Testing
and PTT Telecom.
Our department is one of the key locations in the NWO-funded Priority Programme
'Language and Speech Technology', which aims at combining fundamental research in the
fields of automatic speech recognition, natural language processing and dialogue
management in an operational demonstration version of an automated system that provides
information about public transport over the telephone. In the framework of the NWO
programme, our department will concentrate its efforts on automatic speech recognition,
i.e., acoustic decoding and modelling pronunciation variants.
Closely connected to the NWO project is the Language Engineering (LE) project
Automatic Railway Information Systems for Europe' (ARISE), which aims at building
multi-lingual demonstration versions of telephone-based automatic travel information
systems for public transport. The collaboration with Philips Dialogue Systems and PTT
Telecom that aimed at the implementation of the first operational demonstration version of
such a system for the Dutch language was continued.
The contract with KPN Research in the field of text-to-speech conversion was renewed.
Work continued, and focused on enriching texts with information that should help a text-to-speech system to compute optimal prosody.
The research on corpus linguistics showed steady progress over the year 1996. Prof. dr. J.
Aarts has spent the second half of the year as a guest researcher at the Centre for
Advanced Study of the Norwegian Academy.
In these proceedings we present a general alphabetical list of publications that appeared in
1996, an alphabetical list of presentations given in 1996 of which no written publications
have yet appeared, the abstracts of dissertations that were defended in 1996, and abstracts
of publications by staff members. In addition, a number of reports are included on recent
or current research carried out by members of the department which have not (yet) been
considered for publication elsewhere. Because the department is an amalgamation of three
sections, it has been decided to present the abstracts of publications accordingly. They can
be found under the headers Computational Linguistics, Corpus Linguistics, and
