The ensuing study examined the impact of Parkinson disease (PD) on the duration of CV syllables in different positions within phrases and the distribution of final lengthening (FL) on syllable subcomponents. Two main tendenciess emerged:1) PD patients produced normal FL and 2) FL effects can be attributed primarily to vowels. These findings suggest that PD speakers had no difficulty with FL and that there is a progressive lengthening across the subconstituents of the final syllable. More fundamentally, these results indicate that the syntactic function of prosody is intact in PD patients at least at the early and mild stages of the disease.
