Циљ овог истраживања је био да се утврде акустичке карактеристике гласа и говора испитаника са атаксичном дизартријом и да се испита у којој мери се оне разликују од карактеристика типичних говорника. Узорак је чинило 30 пацијената са атаксичном дизартријом, узраста од 21 до 82 године (АС=56.07). Применом компјутерског програма за мултидимензионалну анализу гласа (MDVP) утврђене су вредности 10 акустичких параметара гласа за сваки пол појединачно. Истим програмом, на основу читања Балансираног текста, добијене су фреквенцијске вредности прва два форманта свих пет вокала српског језика. Резултати анализе су показали статистички значајне разлике у вредностима акустичких параметара између испитаника са атаксичном дизартријом и референтних вредности које важе за типичне говорнике, а које је генерисао MDVP. Разлике су утврђене на параметрима који указују на варијабилност фреквенције гласа (F0, Fhi, Flo, STD, Jitt, vF0), варијабилност интензитета гласа (Shim и vAm), и на присуство прекида у гласу (DVB) и перода без гласа (DUV). Такође, статистички значајна разлика између испитаника са атаксичном дизартријом и типичних говорника постојала је на другом форманту (F2) вокала /Е/ (p<0.01), вокала /И/ (p<0.01) и вокала /У/ (p<0.05). Значајна одступања од норми које важе за типичне говорнике указују на озбиљне промене које су присутне у гласу и говору особа са атаксичном дизартријом.
