Oropharyngeal dysphagia in Parkinson’s disease: potential utility of speech acoustic analysis in detection and evaluation of swallowing impairment progression

Speech acoustic analysis could be useful in everyday clinical practice for performing non-invasive dysphagia screening tests in PD patients, especially when an endoscopic examination is unavailable. Results obtained in the study require further validation in larger cohorts. However, if confirmed, this tool could be used to identify patients who potentially require an invasive examination of swallowing for individualized dysphagia management.
