;;; *** Converted to new Relation architecture -- but not checked yet -- awb
;;; -> crude (beta) checking: gm in Dec. 98
;;;
;;; -> fixed TAKEOVER bug that used time value
;;; as pitch target (!) - MDS 1/02
;;; -> hacked around bunches of target overlap problems - MDS 1/02
;;; -> added primitive pitch range controls
;;;
;;; Known problems and bugs:
;;; Can't currently use voicing intervals which cross syllable boundaries,
;;; so pre/post-nuclear tones are currently places 0.2s before/after the
;;; nuclear tone even if no voicing occurs. Failing this they default a
;;; percentage of the voicing for that syllable.
;;;
;;; Don't know about target points ahead of the current syllable.
;;; (As you need to know what comes before them to calculate them)
;;; So: post accent tones are placed 0.2 ahead if following syllable exists
;;; ends before 0.2 from starred target and is not accented
;;; The H-target of the H+!H* is 0.2 sec instead of 0.15 sec before
;;; starred tone.
;;;
;;; Multi-utterance input has not been tested.
;;;
;;; !H- does not generate any targets
;;;
;;; Unfortunaltely some other modules may decide to put pauses in the
;;; middle of a phrase
;;;
;;; valleys are not tested yet
