Speech, Linguistic and Acoustic Markers in Parkinson's Disease

Speech, Linguistic and Acoustic Markers in Parkinson's Disease

The Investigators aim to identify speech and language markers that provide information on cognitive function and predict cognitive decline in Parkinson's disease. The Investigators will administer speech tasks and cognitive assessments to participants with Parkinson's disease and healthy controls. The Investigators will also explore the associations between genetic factors and speech and cognitive status in Parkinson's disease.
