Abstract

Understanding the fine details of children’s speech and gestural characteristics helps, among other things, in creating natural computer interfaces. We analyze the acoustic, lexical/non‐lexical and spoken/gestural discourse characteristics of young children’s speech using audio‐video data gathered using a Wizard of Oz technique from 4 to 6 year old children engaged in resolving a series of age‐appropriate cognitive challenges.
