| Abstract: | Performers could benefit by knowing in advance and by objective means, what vocal requirements for a particular role or performance are potentially harmful to them. By combining the concept of the “phonetogram” (F0 — SPL Profile) with automatic pitch extraction of vocal performances, a contour of the vocal performance demands can be superimposed on the profile of the individual's vocal capabilities. Vocal productions that are near to or exceeding the vocal capabilities of a performer can be presumed to be potentially hazardous. Likewise, performance demands that are clearly within the profile of a given individual can be presumed to be nonhazardous with respect to pitch and amplitude range. |
