The two important purposes of public speaking

                                                                                                                                Informative  speeches  are  meant  to  give  the audience new or additional information on a relative subject.  Sea  Power  presentations  would  qualify  for informative  speeches.  A  speech  to  local  educators on  educational  opportunities  in  the  Navy  would  be another  example  of  an  informative  speech.
    Entertaining  speeches  are  meant  to  amuse  the audience  and  provide  enjoyment.  Rarely  is  this purpose   used   alone. In   the   area   of   recruiting, entertainment will be secondary to one of the other purposes  of  public  speaking.  Acknowledging  it  as  a secondary purpose to your speech can have obvious benefits.  People  normally  will  pay  closer  attention to  a  speech  that  also  provides  some  enjoyment.
