Prosodic and Segmental Correlates of Spontaneous Dutch Speech in Patients with Parkinson's Disease: A Pilot Study

Vass Verkhodanova, Matt Coler


This study investigates the acoustic correlates of prosody and vowel articulation in Dutch individuals with Parkinson's Disease (PD). We compared prosodic and segmental acoustic measures in spontaneous monologues in PD patients to those in elderly healthy controls matched for age and gender. For the prosodic measurements of pitch variability, span and speech rate, we analysed fundamental frequency and intensity. For articulation measurements, the first two formants were calculated from Dutch corner vowels extracted from the speech signal. Results show a monopitch trend, reduced speech rate, centralization of the formant frequencies and reduced first formant variability in individuals with PD compared to control group.
