ABSTRACT

This manual describes the use of the CLAN program. The acronym CLAN stands for Computerized Language Analysis. It is a program that is designed specifically to analyze data transcribed in the format of the Child Language Data Exchange System (CHILDES). CLAN was written by Leonid Spektor at Carnegie Mellon University. The current version uses a graphic user interface and runs on both Macintosh and Windows machines. Earlier versions also ran on DOS and Unix without a graphic user interface. CLAN allows you to perform a large number of automatic analyses on transcript data. The analyses include frequency counts, word searches, co-occurrence analyses, mean length of utterance (MLU) counts, interactional analyses, text changes, and morphosyntactic analysis.
