This work contains an outline of theoretical basics of voice physiology and pathological changes in speech caused by PD and dysarthria. The selection of linguistic material was characterized according to the place and manner of articulation in the phonetic system of Polish. Another section of this work contains the description of the applied methods of voice recording and preliminary voice analysis e.g. continuous sound analysis and changes in the realization of sounds.
