The corpus consists of 60 transcripts from interactions in everyday contexts between 6 children and their caregivers (10 transcripts per child), recorded longitudinally, for the period when the children are 18 to 27 months of age. All six children are growing up in middle class environments, in Sweden and Thailand (Bangkok area) respectively. The videos of the corpus are linked to the transcripts, on an utterance-by-utterance basis using the software CLAN (MacWhinney 2000). This makes it suitable, among other things, for studies of interaction between verbal and gestural communication.
