The examination was carried out on patients of CM-UJ clinic in Krakow who suffered from neurodegenerative disease with the damage of the extrapiramidal system with dysarthria-type changes in speech. Control examinations of healthy persons have also been carried out. The elements whose realization was tested had been chosen based on the linguistic knowledge in the scope of phonetics as well as on experience resulting from longterm practice as a speech pathologist. The linguistic material was selected in such a way as to pinpoint voice changes characteristic for patients with dysarthria. During the examination, phrases based on Polish idioms were also recorded for further analyses.
