Articulatory Imprecision in Dysarthria Following Childhood Cerebellar Tumor: A Perceptual and Acoustic Investigation of Three Male Participants.

Articulatory Imprecision in Dysarthria Following Childhood Cerebellar Tumor: A Perceptual and Acoustic Investigation of Three Male Participants.

Articulatory imprecision has been documented as a key perceptual feature of the dysarthria associated with childhood cerebellar tumor (CCT). As yet the underlying acoustic and physiological characteristics of motor speech production that contribute to this perceptual feature have not been identified. The aim of the current study was to describe perceptual and acoustic characteristics of consonant production in three children with dysarthria associated with CCT. The results indicated that in all three cases the timing of articulatory movements during stop consonant production differed from that measured in a control group of same-age peers. The impact of cerebellar lesions in adulthood on articulatory gestures is used as a reference for discussing the findings of the current study with similarities evident. Also discussed are future research directions for examining the underlying acoustic or physiological basis for articulatory imprecision in children with dysarthria associated with CCT. **********
