AB Under  normal  circumstances,  the  respiratory  system  supplies  the  aeromechanical  drive  that  allows  the  vocal  folds,  tongue,  lips,  and  other  structures  to  create  the  sounds  of  speech.  Although  a  simplification,  this  drive  can  be  understood  as  the  tracheal  pressure.  Usually  this  pressure  is  exquisitely  and  actively  controlled  by  muscles  of  the  chest  wall.  When  speech  is  produced  with  ventilator  support,  however,  the  ventilator  and  the  respiratory  system  must  work  together  to  produce  the  pressure  that  drives  speech  production.  In  most  cases,  this  pressure  is  markedly  different  from  that  of  normal  speech  production.  As  a  result,  the  act  of  speaking  can  be  challenging  for  patients,  and  they  often  require  assistance  from  their  pulmonologists,  respiratory  therapists,  and  speech-language  pathologists.  The  views  presented  here  are  that  patients  should  be  enabled  to  speak  whenever  possible,  and  that  ventilator-supported  speech  can  often  be  improved  by  using  interventions  such  as  those  described  in  this  chapter.
