;;; 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
