Dysprosody represents an essential part of the lack of speech intelligibility in Parkinson disease. To date, patients’ management has been based on two therapeutic interventions: L-DOPA medication and/or sub-thalamic nucleus (STN) stimulation. Herein, we studied speech production in two groups of ten patients (one group for each treatment), by means of three prosodic parameters: pitch, intensity, and duration.
The results of this study show a clear effect only on the pitch parameter (mean F0 and F0 standard deviation) with either treatment: L-DOPA or STN stimulation. No significant change was obtained on either intensity or duration with these treatments.
