Effects of loudness and complex speech on spataial and temporal precision in Parkinson's Disease

By Mariam Hartinger, William J Hardcastle and Fiona Gardiner


The paper presents preliminary results of a speech\ud motor control study of hypokinetic dysarthria in\ud Parkinson’s disease (PD). By means of EPG, the\ud tongue contacts of two speakers with PD and two\ud control speakers during the production of target\ud words containing initial /t/ stops were analysed in\ud normal and loud condition as well as in complex\ud sentences. The preliminary results showed no\ud effects of increasing loudness on duration and on\ud the number of tongue contacts in speakers with\ud PD. Furthermore, frication of the stop /p/ to [f] was\ud found for one speaker in the acoustic analysis
