Modern medicine calls for new diagnostic methods. Emphasis is placed on non-invasive methods. In addition, they should be characterized by high efficiency, which is a combination difficult to predict. In this area signal processing offers the greatest potential. It is used in many branches of medicine. This article presents one of the possible uses of signal processing, focused on the pathologies of voice, resulting from brain damage caused by vascular problems. Group of 41 patients neurology branch was recorded, with indications of ischaemic stroke, or hemorrhagic. The results clearly indicate the possibility of using the selected voice signal processing algorithms.

Index Terms. Signal processing, voice pathology, stroke, vocal track filter
