Voice onset time in Norwegian infant-directed speech over development

Abstract

The current study will examine the voice onset time (VOT) of stop consonants in infant-directed speech (IDS) to 6, 9 and 12-month-old Norwegian infants, and will assess whether the articulatory properties of IDS related to VOT (difference in length, difference in contrast between voiced and voiceless etc.) are related to the infants' production of stop consonants. The data was collected at the BabyLing lab at the University of Oslo, Norway, from parents speaking Norwegian, and parental input was recorded in the lab. Both IDS and ADS were elicited via a storybook reading task from the child's main caregiver that was either the child's mother or father
