Abstract

The goals of lateral production are complex and imperfectly understood, partly because of the limitations of existing data. Structural Magnetic Resonance Imaging provides rich information about details of lateral production not available using other methods. /l/-articulation by a British English speaker was examined in three vowel contexts using real-time and volumetric Magnetic Resonance Imaging. Onset of lateralisation was characterized acoustically by decreased intensity and development of anti-formants, independent of the degree of tongue dorsum retraction and lingual elongation in different coarticulatory contexts. These patterns suggest that, for this speaker, active laterali channel formation is a primary goal of clear-/l/ production.
