ACQDIV Database


What is ACQDIV [ˈækdɪv] Database?

The ACQDIV Database brings together 17 corpora of first language acquisition, representing 15 maximally diverse languages, in a formally and semantically standardized format. It contains video and audio recordings, transcribed speech, and linguistic annotations from these corpora. The database is created and maintained by the TTF DataScience of the NCCR and the UZH ACQDIV Lab, led by Prof. Sabine Stoll.

To learn more about the corpus’ linguistic design, its structure, and its technical realization, please read the corpus manual.

What for?

  • Studying typological diversity in language acquisition
  • Identifying universal cognitive processes that enable language acquisition
  • Investigating correlations between the acquisition of linguistic features and the surrounding environment
