This investigation explored voice use and perception of use in singers as compared with non-singers at the university. Students recorded the amount and type of their voice use for forty-eight hours. They made judgments about their use and whether a voice disturbance was present. Each student was taped, and tapes were judged for disturbances. It was hypothesized that singers would have greater voice use and awareness than non-singers and experienced singers would have greater voice use and awareness than less experienced singers. Singers used their voices more than non-singers, but there were no differences in awareness. No differences between singer groups were noted. There was a high incidence of voice disturbances in all groups. Suggestions for future research were made.
