Objective Acoustic Quantification of Phonatory Dysfunction in Huntington's Disease

Popis výsledku v původním jazyce

Purpose: Although speech motor changes are reported as a common sign of Huntington's disease (HD), the most prominent signs of voice dysfunction remain unknown. The aim of the current study was to explore specific changes in phonatory function in subjects with HD. Method: 34 subjects with HD and 34 age- and sex-matched healthy controls were examined. Participants performed sustained vowel phonation for subsequent analyses of airflow insufficiency, aperiodicity, irregular vibrations of vocal folds, signal perturbations, increased noise, and articulation deficiency. In total, 272 phonations were collected and 12 voice parameters were extracted. Subsequently, a predictive model was built to find the most salient patterns of voice disorders in HD. The results were also correlated with disease severity according to the Unified HD Rating Scale (UHDRS) motor score. Results: Subjects with HD showed deterioration in all investigated phonatory functions. Irregular pitch fluctuations, sudden phon
