Centre for Language and Speech Technology

We are CLST, the Centre for Language and Speech Technology. We are committed to the development of language and speech technology in an innovative way. Our researchers are experts in research, application development and consultancy. They carry out projects for national and international collaborations and on assignment for commercial parties.

Making language and speech technology available for everyone

The amount of information available in our digitised society is constantly increasing and has a huge impact on our daily lives. In order to ensure that everyone - the elderly, young people, natives, immigrants, the highly educated, the poorly educated, people with communication problems, etc. - has access to this data and can (continue to) participate in our information society, CLST joins forces in four research areas:

Data on laptop screen

Communication-driven knowledge extraction

Language learning & language teaching

Collaboration in innovation

CLST has created a solid network for collaborations and project proposals to extend the research outside the borders of the institute. CLST works together with international or national acknowledged research institutes, industry, societal institutions and other potential users. In addition, the institute is always looking for new partners to combine powers to create innovative research and products that contribute to society.
