This essay examines the art of oral interpretation from a "vocal" perspective--that is, it focuses on the crucial nature of vocal dimensions in oral interpretation. Moreover, the essay argues for an interpreter's hierarchy of vocal needs (modeled after Abraham Maslow's 1970 theory). The interpreter's hierarchy of vocal needs involves basic comprehension, refinement, and other higher level needs. In particular, the essay: (1) briefly reviews selective theoretical dimensions of voice development; (2) offers a speech communication professor's personal perspective on the subject; and (3) provides suggestions for the future, including the necessity to bridge the gap between the leading theorists of oral interpretation and its competitive practice. Contains 14 references and 2 figures outlining "Maslow's Hierarchy of Needs" and "Interpreter's Hierarchy of Vocal Needs." (Author/NKA)
