Dysprosody represents an essentiel part of speech intelligibility in Parkinson disease. To date the patients' management is based on two therapeutic interventions: the L-DOPA medication and/or the sub-thalamic stimulation. We study the speech production in two groups of ten patients (one group for each treatment), considering the prosodic parameters; pitch, intensity and duration.
The results of this study show a clear effect only on the pitch parameter (mean F0 and tonal extent) either with L-DOPA or with STN stimulation. No significant change are obtained with these treatments on intensity and duration.
