This research is a first step toward characterizing motor control and coordination difficulties of dysarthric speakers through the development of acoustic measures which reflect articulatory movements. Aspects of dysarthric stop-consonant production, including primary articulator placement and rate of movement, laryngeal function and the respiratory system, are assessed using perceptual and acoustic data. Acoustic data were obtained from eight adults (4M,4F) with dysarthria (etiologies cerebral palsy, cerebellar ataxia and paralysis) and eight adults (4M,4F) with normal speech and hearing. Subjects recorded isolated, single-syllable utterances containing a word-initial stop followed by a vowel. Auditory-perceptual evaluations of type of voicing, place and manner of articulation, presence of a precursor, and production quality were collected. Visual-perceptual spectrogram assessment was performed and ratings assigned to the following spectrographic attributes: precursor, prevoicing, abruptness of release, time course of release, voice onset time (VOT), and F1 and F
