Abstract
The United States Bureau of Labor Statistics and other sources were consulted about
the percentages of the working population that we identified as professional voice
users. The largest percentage may be in sales and sales-related occupations (13%),
but the exact breakdown of those who approach their clients vocally rather than by
mail is still uncertain. The second largest population is teachers, who comprise 4.2%
percent of the U.S. workforce (1994 statistic). Teachers have been identified as having
the greatest incidence of voice disorders. Population data are also given for professional
voice users who could present a significant hazard to public safety if their vocal
communication skills were severely impaired.
