Syllable level organization has been evidenced in the articulatory movement patterns in different languages [C. P. Browman and L. Goldstein, Producing Speech: Contemporary Issues, 19–34 (1995); R. A. Krakow, ‘‘The articulatory organization of syllables: A kinematic analysis of labial and velar gestures,’’ Ph.D. dissertation, Yale University (1989); Q. E. Wang, ‘‘Are syllables units of speech motor organization?—A kinematic analysis of labial and velar gestures in Cantonese,’’ Ph.D. dissertation, University of Connecticut (1995)]. This study analyzed speech samples produced by nondemented individuals with idiopathic Parkinson’s disease (Hoehn and Yahr stage 2–3) who underwent posteroventral pallidotomy. The data were collected with the patients on and off their medications as well as pre- and post-operatively. The preliminary results indicated that the patients were able to produce stimuli with syllable-initial nasals with less difficulty than those containing syllable-final nasals, and as the patients’ motor performance improved, their ability to produce the stimuli with syllable-final nasals also improved. This may suggest that the speech motor programming and execution are different for the phonemically identical phonemes in syllable-initial and syllable-final positions.
