ABSTRACT |
Background and Objectives The present study reports on the nature of the prosodic disturbances in subjects with dysarthria compared with normal speakers. Methods This study, based on analysis of intonation stimulability for alternative question sentence, reports on temporal and intonational components for 16 subjects with dysarthria and 13 healthy controls. Results Prosodic features that were preserved in the subjects with dysarthria were pause proportion, ㎃ slope for sentence and all of intonation slope in sentential Q2 final word. However, the subjects with dysarthria had reduced speaking and articulation rates, reduced F₀ slope and q-tone slope for sentence, and all of intonation slope in sentential Q1 final word. Discussion and Conclusion The results showed that specifically, in rising intonation, subjects with dysarthria had slower speech rate and more gradual intonation slope than normal speakers. |
