Prosodic Characteristics of Mandarin Declarative and Interrogative Utterances in Parkinson’s Disease

Lei Liu, Meng Jian, Wentao Gu


This work investigated the prosodic characteristics of declarative and interrogative utterances produced by speakers with Parkinson’s disease (PD), in comparison to healthy controls (HC). Forty native speakers of Mandarin, including 20 PDs and 20 age-matched HCs, recorded 32 utterances varying in sentence type, sentence length, and sentence-final tone. SS-ANOVA was used to show the F0 contours and the global and final-syllable F0 level, F0 slope, speech rate, and intensity ratio were statistically analyzed using linear mixed-effects models. For the HC group, interrogative utterances showed a significantly higher mean F0 than declarative utterances. The PD group exhibited no significant F0 difference between declarative and interrogative utterances, coinciding with our subjective impression on PD’s monotonous voice of tone. This suggests that PD’s ability to control fundamental frequency degraded in comparison to HC. Also, the PD group produced significantly faster speech, especially final syllable, than the HC group, suggesting that PD’s articulatory control degraded at the end of an utterance.
