Edinburgh infant language corpus

A naturalistic speech corpus collected from 47 infants (from 9 to 21 months) and their caregivers

This corpus was collected as part of the project entitled 'The role of baby-talk words in early language' funded by the ESRC in order to investigate the relationship between the phonological profile of the lexical input infants receive and their subsequent lexical development. The corpus consists of audio-recordings made at the home of 47 infants in naturally occurring interaction between the infants and their caregivers (primarily their parents) when the infants were 9, 15 and 21 months of age. The 9-month recordings have been transcribed in CHAT format and made available through the CHILDES system. In addition to the recordings, the infants' vocabulary knowledge has been assessed through parental reporting (using a CDI questionnaire) at each of the 3 age points.
