This paper reports on a first attempt at adopting a new perspective in characterizing speech disorders in Parkinson's Disease (PD) based on individual patient profiles. Acoustic data were collected on 13 Belgian French speakers with PD, 6 male, 7 female, aged 45-81 and 50 healthy controls (HC) using the "MonPaGe" protocol (Fougeron et al., LREC18). In this protocol, various kinds of linguistic material are recorded in different speech conditions, in order to assess multiple speech dimensions for each speaker. First, we compared a variety of voice and speech parameters across groups (HC vs. PD patients). Second, we examined individual profiles of PD patients. Results showed that as a group PD participants most systematically differed from HC in terms of speech tempo and rythm. Moreover, the analysis of individual profiles revealed that other parameters, related to pneumophonatory control and linguistic prosody, were valuable to describe the speech specificities of several PD patients.
