In this paper, we focus on the case of palatal glides produced by ten French-speaking parkinsonian subjects. This research is a part of a project whose final aim is the building of a comprehensive study of the various ways in which Parkinsonian pathologies can exert influence on speech.
   The acoustic analyzes (formants tracks in the DC-4000 Hz range) were performed by DSP 5500 and CSL 4300 kay stations.It revealed that the glides are characterized by alterations of the acoustic variation during the time-course of the segment production.
