CHILDES is mainly used for analyzing the language of young children and speech of adults directed to them.
[1] CHILDES is currently directed and maintained by Brian MacWhinney at Carnegie Mellon University.
In addition to discourse level transcription, the CHAT system also has options for phonological and morphological analysis.
The CLAN program was developed by Leonid Spektor and aids in transcription and analysis of the child language data.
