Perceptual judgement method is frequently used in evaluating dysarthric speech. Although most of speech pathologists and researchers focus on the 38 perceptual features provided by Darley, Aronson & Brown(1969) during evaluation, there are additional characteristics that may be useful to describe dysarthria in literature. We reviewed previous dysarthria literature and selected 46 perceptual characteristics that could be examined at various subsystems of speech production. We also provided explanations and rationale for the rating method for each of the perceptual characteristics. This attempt might aid to offer a basic ground for developing a diagnostic tool of dysarthria.
