According to Maskeliūnas, a researcher at KTU's Department of Multimedia Engineering, as motor activity decreases, so does the function of the vocal cords, diaphragm, and lungs: "Changes in speech often occur even earlier than motor function disorders, which is why the altered speech might be the first sign of the disease."
