Over half of US children are enrolled in preschools, where the quantity and quality of language input from teachers are likely to affect children’s language development. Leveraging repeated objective measurements, we examined the rate per minute and phonemic diversity of child and teacher speech-related vocalizations in preschool classrooms and their association with children’s end-of-year receptive and expressive language abilities measured with the Preschool Language Scales (PLS-5).

In this Developmental Science journal article, Daniel Messinger, Lynn Perry, et al., studied phonemic diversity and how it affects language development in preschool children. Their results highlighted a specific feature of the classroom language environment—phonemic diversity—as a promising correlate of children’s developing language capacities.
