This study was designed to investigate the development of articulatory timing from mid-childhood to late adolescence. Productions of sentences containing /t/, /l/, /s/, and /k/ were produced by 48 children and adults (aged 6-38 years) and captured using the Reading Electropalatography3 (EPG3) system. Mean duration of the sentences and the approach, closure/stable constriction, and release phases of consonant articulation were calculated. In addition, temporal coordination of lingual gestures and the intra-subject articulatory timing variation were investigated across the ages. Results reveal some distinct differences in duration and temporal coordination of lingual gestures between 6- to 7-year-olds and mature speakers, with continual refinement of articulatory control indicated into late adolescence. Differences in articulatory stability, in contrast, were not significant. The present findings may form a platform for development of a more descriptive model of motor speech development.
