Studies concerning the effectiveness of voice are lacking. There is little experimental verification that therapy techniques actually achieve specific change in abusive vocal function. Guidelines are presented regarding conceptual and methodological consideration for future investigations. Divergent terminology, philosophy, and issues of voice therapy are presented to serve as an overview and as a basis for research direction. Suggestions are offered for selecting experimental designs.
