Voice Disorders Assessment of Chinese Pronunciation Parkinson's Disease Dataset

People with Parkinson's disease (PD) have significant voice disorders and can be diagnosed by sustained vowels. There are few studies of PD with sustained vowels in Chinese phonatory. This paper aims to study the differences among different vowels in Chinese. We collect a sustained vowel dataset of patients with PD in China with multiple vowel types, and use SVM and KNN algorithms to compare and analyze Chinese dataset and other language dataset. The experimental results show differences between Chinese and other languages in PD detection with the same classifiers and sustained vowels, and the best detected vowel in Chinese pronunciation is the vowel /u/. In this study, two main conclusions have been drawn. Firstly, different sustained vowels have different effects on the detection of PD in Chinese. Secondly, different language pronunciations of the same sustained vowel have varied effects on the detection of PD.
