The more-than-half-a-century-long research tradition into Infant-Directed Speech (IDS) describes how caregivers speak to infants, with the aim to understand why IDS sounds different from Adult-Directed Speech (ADS) and how it may impact infants’ language and socio-emotional development. In this course, we will look at IDS through a phonetician's lens. We will reassess its acoustic-phonetic properties and their potential causes in light of the conflicts in the IDS literature and the broader knowledge of other speech registers. Guided group discussions will result in new research questions about the language/context/speaker specificity of IDS and the impact of this register on infants.
The structure is as follows:
Both sessions will include measure-your-own-IDS activities and invitations for participants to propose new directions for studying IDS.
