Implementation of pronunciation-generation module from spelling for
Old English.
Author: Benwing
Generally, the user should supply the spelling, properly marked up with
macrons for long vowels, and ċ ġ ċġ sċ for soft versions of these consonants.
In addition, the following symbols can be used:
-- acute accent on a vowel to override the position of primary stress
-- (in a diphthong, put it over the first vowel)
-- grave accent to add secondary stress
-- circumflex to force no stress on the word or prefix (e.g. in a compound)
-- . (period) to force a syllable boundary
-- - (hyphen) to force a prefix/word or word/word boundary in a compound word;
-- the result will be displayed as a single word but the consonants on
-- either side treated as if they occurred at the beginning/end of the word
-- + (plus) is the opposite of -; it forces a prefix/word or word/word boundary
-- to *NOT* occur when it otherwise would
-- _ (underscore) to force the letters on either side to be interpreted
-- independently, when the combination of the two would normally have a
-- special meaning
FIXME:
1. Implement < and > which works like - but don't trigger secondary stress
(< after a prefix, > before a suffix) (DONE)
2. Recognize -lēas and -l[iī][cċ] as suffixes. (DONE)
2b. Recognize -fæst, -ful, -full as suffixes (so no voicing of initial
fricative). (DONE)
3. If explicit syllable boundary in cluster after prefix, don't recognize as
prefix (hence ġeddung could be written ġed.dung, bedreda bed.reda) (DONE)
4. Two bugs in swīþfèrhþ: missing initial stress, front h should be back (DONE)
5. Check Urszag's code changes for /h/. (DONE)
6. Bug in wasċan; probably sċ between vowels should be ʃʃ (DONE)
7. Bug in ġeddung, doesn't have allowed onset with ġe-ddung (DONE)
8. āxiġendlīc -- x is not an allowed onset (DONE)
9. Handle prefixes/suffixes denoted with initial/final hyphen -- shouldn't
trigger automatic stress when multisyllabic. (DONE)
10. Don't remove user-specified accents on monosyllabic words. (DONE)
11. Final -þu/-þo after a consonant should always be voiceless (but should be
overridable). (DONE; OVERRIDABLE THROUGH "EXPLICIT ALLOPHONE" NOTATION)
12. Fricative voiced between voiced sounds even across prefix/compound
boundary when before (but not after) the boundary. (DONE)
13. Fricative between unstressed vowels should be voiceless (e.g. adesa);
maybe only after the stress? (DONE)
14. Resonant after fricative/stop in a given syllable should be rendered
as syllabic (e.g. ādl [ˈɑːdl̩], botm [botm̥], bōsm, bēacn [ˈbæːɑ̯kn̩];
also -mn e.g stemn /ˈstemn̩/. (DONE, BUT REVERSED)
15. Add aġēn- and onġēan- prefixes with secondary stress for verbs.
(WILL NOT DO)
16. and- (and maybe all others) should be unstressed as verbal prefix.
andswarian is an exception. (DONE)
17. Support multiple pronunciations as separate numbered params. (DONE)
17b. Additional specifiers should follow each pronun as PRONUN<K:V,K2:V2,...>.
This includes the current pos=.
18. Double hh should be pronounced as [xː]. (DONE)
19. Add -bǣre as a suffix with secondary stress. (DONE)
20. Add -līċ(e), lī[cċ]nes(s) as suffixes with secondary stress. -lī[cċ]nes(s)
should behave like -līċ(e) in that what's before is checked to determine
the pos. (DONE)
21. -lēasnes should be a recognized suffix with secondary stress. (DONE)
22. Fix handling of crinċġan, dynċġe, should behave as if ċ isn't there. (DONE)
23. Rewrite to use [[Module:ang-common]]. (DONE)
24. Ignore final period/question mark/exclamation point. (DONE)
25. Implement pos=verbal for handling un-. (DONE)
26. Simplify geminate consonants within a single syllable. (DONE)
27. Implement "explicit allophone" notation, e.g. [s] [z]. (DONE)
28. ''-sian'' should be voiceless in verbs. (DONE)
29. ''-rian'' should have /j/ after short vowels in verbs. (DONE)
30. BUG: Secondary stress not getting applied in ''-lēas'' (see [[aldorleas]]).
QUESTIONS:
1. Should /an/, /on/ be pronounced [ɒn]? Same for /am/, /om/. [NO]
2. Should final /ɣ/ be rendered as [x]? [NO]
3. Should word-final double consonants be simplified in phonetic representation?
Maybe also syllable-final except obstruents before [lr]? [YES]
4. Should we use /x/ instead of /h/? [YES]
5. Should we recognize from- along with fram-? [NO]
6. Should we recognize bi- along with be-? (danger of false positives) [NO]
7. Should fricative be voiced before voicd sound across word boundary?
(dæġes ēage [ˈdæːjez ˈæːɑ̯ɣe]?) [NO]
8. Ask about pronunciation of bræġn, is the n syllabic? It's given as
/ˈbræjn̩/. Similarly, seġl given as /ˈsejl̩/. [NO; HUNDWINE AND URSZAG DISAGREE]
9. Ask about pronunciation of ġeond-, can it be either [eo] or [o]? [UNCLEAR]
10. Is final -ol pronounced [ul] e.g regol [ˈreɣul]? Hundwine has created
entries this way. What about final -oc etc.? [NO]
11. Is final -ian pronounced [jan] or [ian]? Cf. sċyldigian given as
{{IPA|ang|/ˈʃyldiɣiɑn/|/ˈʃyldiɣjɑn/}}. What about spyrian given as /ˈspyr.jɑn/?
[-ian in weak II verbs, -jan in weak I verbs]
12. seht given as /seçt/ but sehtlian given as /ˈsextliɑn/. Which one is
correct? [ç]
13. Final -liċ or -līċ, with or without secondary stress?
14. Should we special-case -sian [sian]? Then we need support for [z] notation
to override phonetics.
