This corpus contains longitudinal child language acquisition data including phonetic transcriptions and sound files from 12 Dutch children between one and two years of age of the start of a one-year-period of data collection. Data were collected during spontaneous play sessions every fortnight. The data are available via CHILDES/Phon:

This corpus contains video recordings of ten Dutch children between 6 months and 3;6 years of age born to deaf parents. These children acquire Sign Language of the Netherlands (NGT) as their first language (next to spoken Dutch). Recordings were made every fortnight, alternating with one video camera (by trained parent) and two video cameras (with a deaf assistant). The data are stored digitized and stored with all relevant metadata in the Language Archive. For details see:

Research groups from the universities of Nijmegen, Amsterdam (UvA), and Utrecht have decided to prepare a nationwide, open access multimedia archive of language pathology data collected in the Netherlands, primarily on Dutch. In this enterprise, as many other research groups as possible, both from universities and care and educational institutes, will be involved. Although data sharing is becoming increasingly important to widen the scope and depth of empirical research in all kinds of areas, no tradition has been established yet in language and speech pathology research. This means that in various places a wealth of relevant and precious language data exists that cannot be easily and optimally accessed and exploited.
