; THDL Phonetics rules for WylieWord.
|
|
|
|
; File format: there are two sections, for rules and exceptions.
|
|
;
|
|
; There is one rule per line. Typically a rule has two parts,
|
|
; separated by a space. The first part is a sequence of letters
|
|
; that, if it appears in a Wylie transliteration, is to be replaced
|
|
; by the second part in the phonetic transcription. The second
|
|
; part can be missing, in which case the first part is simply
|
|
; deleted from transcriptions when found.
|
|
;
|
|
; A semicolon precedes a comment. Blank lines are OK.
|
|
;
|
|
; The rules are applied in the order they appear in this file.
|
|
; Each rule is applied as many times as possible, but we never
|
|
; go back to a previous rule. (This simple rewrite-rule grammar is
|
|
; not sufficient to implement all phonetic schemes, at least not
|
|
; compactly. For example, it would be difficult to capture the
|
|
; effects of preinitial consonants on tone (as in the scheme used
|
|
; in Joe Wilson's book, for instance).) Also note that not even the
|
|
; whole of the present scheme is implemented using these rules. For
|
|
; example, the deletion of prefix and superscript consonants,
|
|
; and of wa-zur, are done in program code, not using the rules here.
|
|
|
|
; This makes e come out é only when the last letter in a "word" (*not*
|
|
; syllable). Our grammar engine is not nearly powerful enough to do
|
|
; this in a clean way.
|
|
<?Enable THDL final é kludge?>

; pronunciation (which may also contain spaces). A semicolon
