  Have you ever thought about your voice and its significance in daily living ?
  
  How do you rate yourself as a voice user?
  
  The Elite Vocal Performer, Level I, is a person for whom even a slight aberration of voice may have dire consequences. Most singers and actors are in this group; the opera singer is the quintessential level I performer.
  The Professional Voice User, Level II, is a person for whom a moderate vocal problem might prevent adequate job performance. This group includes most clergy, teachers, lecturers, receptionists, etc.
  The Non-Vocal Professional, Level III, is a person for whom a severe vocal problem would prevent adequate job performance. This group includes lawyers, physicians, businessmen, business women, etc.
  The Non-Vocal Non-Professional, Level IV, is a person for whom vocal quality is not a prerequisite for adequate job performance. This group includes clerks, laborers, and so forth. Although persons in this group may suffer very significant social liability from a voice disorder, they are not prevented from doing their work.
