;;;  Functions specific to using Festival in cslush part of the OGI toolkit
;;;  The OGI toolkit is a complete dialog building system with speech
;;;  recognition and synthesis (Festival) it is available for free for
;;;  research purposes from
;;;     http://www.cse.ogi.edu/CSLU/toolkit/toolkit.html
;;;
;;;  Note this cslush interface requires you to compile festival
;;;  with tcl (7.6)
;;;
;;;  The functions replace the C++ level functions Jacques H. de Villiers
;;;  <jacques@cse.ogi.edu> from CSLU wrote for the previous version
