Abstract
At the same time young children experience rapid physical growth, they are faced with the challenge of mastering the complexities of speech production. Capturing the dimensions of the vocal tract during early childhood is a crucial step in characterizing early speech acoustics and speech motor control. The present study partially replicates measures of the vocal tract first employed in previous studies. Magnetic resonance images (MRI) were obtained from two 5-year-old and six 6-year-old children. Anatomical measurements of the vertical vocal tract (VT-V), posterior cavity length (PCL), anterior cavity length (ACL) and overall vocal tract length (VTL) are reported for each child. Results are consistent with previous findings, and are foundational for a larger, stratified longitudinal study aiming to characterize the development of individuals’ vocal tract anatomy between 5 and 9 years of age.
