EUDIA research team was created to investigate linguistic variation. At the beginning, the main objective was to study the variation of Basque, to specify the factors, both social and otherwise, that produce this variation and to create research tools.

After a few years, the group expanded and new avenues of research emerged, linked to language didactics and the development of oral competence, therefore, scientific work is currently being carried out to study suprasegmental elements both in reading aloud and in spontaneous texts, in young people, children and people with aprosody.
