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