Abstract In  this  paper,  Arabic  was  investigated  from  the  spe ech  recognition  problem  point  of  view.    We  propose  a  novel  approach  to  build  an  Arabic  automated  speech  recogn ition  system  using  Arabic  environment.  The  system, based  on  the  open source CMU Sphinx-4, was trained using Arabic  characters.
