Description	Dysprosody in Parkinson's disease (PD) is characterized by several symptoms. One of these symptoms is disability to produce precise stress pattern. A group of 20 untreated patients in the early stages of PD was compared to a group of 17 healthy age-matched controls to quantify possible acoustic changes in speech production secondary to PD. All participants produced a standardized speaking task of contrastive stress. The standard used measurements of amplitude, fundamental frequency and duration were performed. Moreover, the novel measurement of Stress Pattern Index (SPI) that combines amplitude, fundamental frequency, and duration characteristics was designed. The measurements of F0 range, Intensity range, Duration, and SPI differentiate between PD and healthy controls (HC) across many conditions in the group of stressed and unstressed tokens. On the other hand, only SPI was sufficiently sensitive to distinguish between PD and HC group for stress tokens that was normalized by normal reading tokens. To summarize, acoustic changes of prosodic stress appear to occur from early stages of PD. Dysprosody in Parkinson's disease (PD) is characterized by several symptoms.
