Perceptual Speech Characteristics of Cerebellar Dysarthria Associated with Lesions in Different Cerebellar Loci

The perceptual method of classifying dysarthria is considered the “gold standard” for clinically differentiating the types of dysarthria. Darley et al., 1 pioneered the use of perceptual classification system to identify clusters of salient perceptual characteristics in speech that are associated with lesions in the central and peripheral nervous system. This system is also popularly referred to as the “Mayo Clinic Dysarthria Research” 1 . Many researchers who investigate the acoustic and physiologic bases of dysarthrias also use the perceptual classification system. The present study attempts to analyse the perceptual speech characteristics in dysarthria associated with lesions in different cerebellar loci.
