The present study examines the spectral and temporal characteristics of Infant Directed Speech (IDS) vowels spoken to young children in the Indigenous Australian language Warlpiri. The results show that vowel hyperarticulation, temporal expansion and pitch raising are characteristics of Warlpiri IDS to children in the third year of life. The results also suggest that vowel space fronting may be a common strategy, and that vowel space and durational expansion may play a didactic role in IDS young children at an age characterised by rapid vocabulary expansion and increased multiword utterances.
