Abstract

|
|
Background & 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 F? slope and q-tone slope for sentence, and all of intonation slope in sentential Q1 final word.
Discussion & Conclusion: The results showed that specifically, in rising intonation, subjects with dysarthria had slower speech rate and more gradual intonation slope than normal speakers.
