Intonation och rytm i talet hos personer med Parkinsons sjukdom - en longitudinell jämförelse mellan sjukdomens effekter och effekter av behandling
Title [en]
Intonation and rhythm in speech of patients with Parkinson´s disease - a longitudinal investigation of effects of the disease and its treatment
Abstract [sv]
The manifestation of intonation and rhythm require a careful coordination of articulators in order to achieve appropriate perceptual properties. A number of systems required for appropriate manifestation of intonation and rhythm are deteriorated in patients with Parkinson?s disease (PD). Further, some of the available treatment options (Levodopa, Deep Brain Stimulation, DBS) have shown both positive and adverse effects on features of speech production related to intonation and rhythm. The aim of the present project is to provide a detailed analysis of the intonation and rhythm in speakers due to PD and due to treatment using Levodopa or DBS in either the subthalamic nucleus (STN) or the caudal zona incerta (cZi). Acoustic measurements related to intonation and rhythm will be collected from an existing set of recordings of 31 patients made before surgery (with and without medication) and 6 and 12 months after surgery (with and without stimulation of either STN or cZi) following a comprehensive recording protocol. The processing of recordings will be done in a recursive manner, where each iteration extracting a more detailed view of the material in terms of intonation and rhythm, while at the same time validating results from the previous iteration. The project will thereby provide a comprehensive and highly verified view of the prosodic system of speakers with Parkinson?s disease, as well as effects of treatments.
