The Project

 SENFM will examine how infants' vocal development during the first year of life interacts with their early language environment to provide feedback that can be drawn upon in acquiring and developing speech sounds and, ultimately, producing first words. The project will involve working with a cohort of families and their infants aged 2-18 months to collect home-recorded data, with accompanying experiments in the York BabyLab. We will be implementing an existing methodology - ultrasound imaging of the tongue - to a new population - young infants - to understand changes taking place in the speech articulators (in this case, tongue and lips) over the course of development, and how these are affected by different language environments. Ultimately, we are aiming to test whether infants draw on sensorimotor feedback (the simultaneous sensory events experienced during vocal production, such as proprioception, muscular function, and auditory input) to drive their language learning.
