Annual Report 1999
Table of Contents
Our contacts with other research institutions in Sweden and internationally
are well developed. Of major importance in this respect is our scientific journal, the TMH-QPSR, which has four
volumes/year. Close to 900 copies are distributed to 56 countries. Abstracts from the contributions in the 1999
issues are included in this report.
We have several guest researchers staying half a year or longer, and
we participate in a substantial number of international symposia, conferences, and workshops, as listed in the
The Speech group is engaged in European co-operation within the COST-program
(European Co-operation in the Field of Science and Technical Research) in projects on
- speech recognition
(COST 249, Continuous speech recognition over the telephone),
- speaker recognition
(COST 250, Speaker recognition in telephony), and
- speech synthesis (COST
258 - Naturalness of synthetic speech).
- We are also part of several other European projects, such as projects
- speaker recognition
- spoken dialogue
The department is the Swedish managing node for Elsnet, the Esprit-sponsored European Network for
Language and Speech Research.
Within the current EC-program TIDE (Technology Initiative for Disabled and Elderly), we have been engaged in ENABL (ENABler for computer-based
vocational tasks with Language and peech).
Another exponent of increased European co-operation in the speech research
area is ESCA
(European Speech Communication Association), where we are represented on the board. ESCA has recently been redefined
as the international organization ISCA.
Outside Europe, we have contacts with several groups on a non-formal
basis. Exchanges of students, guest researchers, shorter visits, and exchange of reports is the normal mode of
operation. Of special interest is the long-lasting close contact with speech researchers at MIT, USA, and the increased contacts
with ATR, Japan.
In the context of ISAAC (International Society for Augmentative and Alternative Communication), we have
been very active, having had a member on the board of both the international organisation and the Swedish chapter.
We have had an important role in extending interdisciplinary contacts
within Sweden, e.g., through almost weekly demonstrations, lectures, and open-house activities for schools and
Swedish dialogue systems (SDS) is studied in co-operation with Linköping, Lund and Gothenburg Universities.
This work is carried out within the "Language Technology
Program" jointly sponsored by NUTEK (Swedish National Board for Industrial and Technical Development) and HSFR (Swedish Council for Research
in the Humanities and Social Sciences).
Contacts with Linköping University have been active, with joint
education in speech technology and a project on spoken dialogue modelling.
We have also close technical and scientific contacts with
- Telia Promotor (Infovox) AB, which markets speech technology products
based on our research and development
- the research department of Telia
- the Swedish Telecom (Telia Research AB)
- Special Instrument AB, which markets the tactile aid "Minivib4"
and some of our aids for speech training;
- Rehabmodul AB
- Svenska ENTER Rehabilitering AB
- Fonema AB
- Statens Institut för Handikappfrågor i Skolan (SIH, the National
Swedish Agency for Special Education), which market aids for motorically handicapped.
- Within the main-phase of CTT we have formal co-operation with fourteen
- Ericsson Radio Systems AB
- Levande Böcker i Norden AB
- PipeBeach AB
- Polycom Technologies AB
- Svenska Handelsbanken AB
- Sveriges Radio AB
- Telia Promotor AB
- Telia Research AB
- Trio Informationssystem AB
- Vattenfall AB, and
- Volvo Teknisk Utveckling AB.
The music group is engaged in cooperation with the following external
- Institute of Linguistics,
- Institut für Stimmforschung,
Hochschule für Musik Carl Maria von Weber, Dresden, Germany
- Italian Cultural Institute,
- Department of Logopedics and Phoniatrics, Huddinge University Hospital, Sweden
- Ecole National Superieure de Télécommunications, Paris
- The Royal Danish Academy of Music,
- The Norwegian State Academy of Music,
- University of Surrey Roehampton,
- Vanderbilt Voice Centre,
Vanderbilt University, Nashville, TN, USA
Research activities associated with these contacts have been described
Hearing Technology Group
The Hearing Technology group is engaged in European co-operation as a
full partner within two projects: LISCOM (Listening Comfort Systems for Hearing-Instruments and Telephones), and
SPECO (A Multimedia Multilingual Teaching and Training System for Speech- and Hearing-Impaired Children). The group
is also an associated partner in the NATASHA project (Network and Tools for the Assessment of Speech/Language and
Hearing Ability). We also maintain a research exchange program with AG Medizinische Physik at the University of
We have close contacts with the hearing-instrument industry. A group
of companies (Danavox, ReSound, and Audiologic) has supported some of our work on signal processing algorithms
for hearing aids.
We maintain close co-operation with Swedish audiological clinics and
with all four educational programmes for clinical general audiologists in Sweden. We participate in teaching and
research supervision related to signal processing in hearing aids and methods for the fitting and evaluation of
personal aids for hearing-impaired persons. We also co-operate with teachers at schools for the deaf concerning
methods for speech training.
