This portal provides access to various Text & Speech processing software services developed by the Centre of Language and Speech Technology or the Humanities Lab of Radboud University Nijmegen.

These tools are accessible for free but do require authentication. They participate in the CLARIAH infrastructure which means you can authenticate using your own institutional login, provided your institution has ties with CLARIN. If your institute is not in the list you can request a CLARIN account. For general questions or comments contact Henk van den Heuvel. For technical issues, contact admin@cls.ru.nl, here you can also request an API key for automated access if you explain your use-case.
