Parameter lain dalam sinyal suara ucapan yang berpengaruh terhadap intonasi adalah power, komponen periodik dan tak periodik sinyal suara.  Dalam penelitian ini, dilakukan manipulasi sinyal suara ucapan hanya pada parameter F₀ sinyal suara ucapan berbahasa Indonesia, sedangkan parameter lain dianggap tetap.
