In Articulatory Phonology the jaw is not controlled individually but serves as an additional articulator to achieve the primary constriction. In this study the timing of jaw and tongue tip gestures for the coronal consonants /s, ʃ, t, d, n, l/ is analysed by means of EMMA. The findings suggest that the tasks of the jaw for the fricatives are to provide a second noise source and to stabilise the tongue position (more pronounced for /s/). For the voiceless stop, the speakers seem to aim at a high jaw position for producing a prominent burst. For /l/ a low jaw position is essential for avoiding lateral contact and for the apical articulation of this sound.
