Stiffness and articulatory overlap in Moroccan Arabic consonant clusters

It has been claimed that patterns of regressive place assimilation in consonant clusters are attributable to the ‘inherent velocities’ primary oral articulators involved. The present study used articulatory data from Moroccan Arabic evaluate whether there were reliable differences peak velocity or measured stiffness based on articulator. Evidence for such was limited. We also evaluated degree overlap could be predicted by combination a C1C2 cluster. Some significant found, but they did not align with assumed inherent rapidity articulators. Lastly, we amount influenced relative velocities closing gestures two-consonant clusters. not. However, when dynamical control parameter same instead velocity, robust effect found. This result suggests settings influence cluster, which is too subject contextual effects as movement amplitude.
