This study provided a quantitative analysis of the kinematic deviances in dysarthria associated with spastic cerebral palsy. Of particular interest were tongue tip movements during alveolar consonant release. Our analysis based on kinematic measures indicated that speakers with spastic dysarthria had a restricted range of articulation and disturbances in articulatory-voicing coordination. The degree of kinematic deviances was greater for lower intelligibility speakers, supporting an association between articulatory dysfunctions and intelligibility in spastic dysarthria.
