CHILDES: Child Language Data Exchange System
The CHILDES Project has focused on the construction of a computerized database for studying child language acquisition. There are currently 230 corpora in the database from 30 different languages comprising transcripts of spontaneous verbal interactions between young children and their parents, playmates and teachers. Many of the transcripts are linked to additional audio and video media files that allow researchers to immediately playback the interactions on the level of individual sentences at any point in the transcript. The project maintains a list of 4,000 child language researchers and students who have used the database, and has records of more than 3,000 published articles based on the use of these materials. The project has also constructed a set of computer programs useful for conducting research into the various levels of language usage including lexicon, syntax, morphology, phonology, discourse and narrative.
