[hts-users:00779] Re: A bug in festival/lib/hts.scm

[Junichi Yamagishi <jyamagis@xxxxxxxxxxxx>]

Hi all,

I additionally found two crucial bugs in the festival/lib/hts.scm.

********Bug 1 of Current Code**********
;  nn.name
  (format ofd "+%s" (if (string-equal "0" (item.feat s "n.n.name"))
                        "x" (item.feat s "n.n.name")))

********Fixed version******************
;  nn.name
  (format ofd "=%s" (if (string-equal "0" (item.feat s "n.n.name"))
                        "x" (item.feat s "n.n.name")))


********Bug 2 of Current Code**********
;  distance from content word in phrase
  (format ofd ";%s"
          (if (string-equal "pau" (item.feat s "name"))
              "x"
              (item.feat s  
"R:SylStructure.parent.parent.R:Word.lisp_distance_to_p_content")))

********Fixed version******************
;  distance from content word in phrase
  (format ofd "#%s"
          (if (string-equal "pau" (item.feat s "name"))
              "x"
              (item.feat s  
"R:SylStructure.parent.parent.R:Word.lisp_distance_to_p_content")))

If you are using any HTS US English voices with festival, please fix.
Quality of synthetic speech would become much better.
