In this article, I present a new strategy for researching stage speech based upon a specific protocol of steps. Developed through a comprehensive study of stage speech investigating breakthrough stagings of Ivan Cankar's drama Hlapci (Eng. The Bondsmen or The Servants) during the last fifty years, the strategy approaches the research of stage speech in a way that is objective (using a combination of audio perception and computer-assisted phonetic analysis) and interdisciplinary (including theatre studies, sociology, and other fields alongside phonetics), while considering the integration of stage speech into directorial concept and its integration with other staging factors (e.g., scenography, mise-en-scene, costumes, music, movement).
