08:30New Horizons in the Study of Language Development

Deb Roy (MIT Media Lab)

Emerging forms of ecologically-valid longitudinal recordings of human behavior and social interaction promise fresh perspectives on age-old questions of child development. In a pilot effort, 240,000 hours of audio and video recordings of one child’s life at home are being analyzed with a focus on language development. To study a corpus of this scale and richness, current methods of developmental sciences are insufficient. New data analysis algorithms and methods for interpretation and computational modeling are under development. Preliminary speech analysis reveals surprising levels of linguistic “finetuning” by caregivers that may provide crucial support for word learning. Ongoing analysis of various other aspects of the corpus aim to model detailed aspects of the child’s language development as a function of learning mechanisms combined with everyday experience. Plans to collect similar corpora from more children based on a streamlined recording system are underway.
