Daimler-Chrysler Research and Technology
Speech Understanding Department, ULM, DE
Experience and competence
DaimlerChrysler is one of the largest German companies. It's core business
is automotive production but it has also been involved with information
technology for many years. A growing area of interest is speech and language
technology for applications in very different fields, ranging from voice
operated mobile telephones to speech dialogue systems for call center automation.
Research in the field of speech understanding systems is carried out
at the research centre in Ulm. The relevant topics addressed are man-machine-interfaces,
communication technology, speech and language understanding and image understanding.
The department of speech understanding systems is active in the whole field
of speech and language processing. Work is done in speech coding, special
signal processing of acoustic speech signals like noise compensation, speech
recognition and synthesis, linguistics, dialogue management and speech
and language based knowledge processing. Prototypical application systems
are realized together with the relevant application departments of the
DaimlerChrysler concern. An additional important field is research in statistical
signal processing including neural networks and knowledge based systems.
DaimlerChrysler has developed the first German speech recognizers called
ADES 1 to 3. These systems were either speaker dependent or speaker independent
isolated word recognizers. One of the first recognizers SPREIN was used
in an IVR system for the European Commissions ECHO information system to
provide telephonic information about projects.
Later on the first speaker adaptive and speaker independent continuous
word recognizers were developed. Another relevant project was the development
of the first German automatic railway information systems, providing all
railway information from the network of the Germand Railway. Further prototyping
systems have been realized for warehouses and other IVR systems. The latest
products developed by DaimlerChrysler are voice operation for mobile telephone
and entertainment in the car and telephone speech recognizers for universal
Role in the Project
General robustness of recognition is the main focus of much current research
at DaimlerChrysler, who are therefore well-placed to provide the industrial
edge to HOARSE and lead the application work of theme 4.
Within the HOARSE programme the closest links will be with Sheffield, IDIAP,
