Implementation of pronunciation-generation module from spelling for German.
Author: Benwing
-------------------- STRESS ----------------
If there are no prefixes or suffixes, the default position of the stress is on the first syllable; e.g. [[arbeiten]]
/ˈaʁbaɪ̯tən/ "to work" or [[hundert]] /ˈhʊndɐt/ "hundert". This may change in the presence of prefixes or suffixes. For
example, the module recognizes the prefix er- as unstressed, and hence in a word like [[Ermächtigung]] /ɛʁˈmɛçtɪɡʊŋ/
"authorization" the stress is instead placed on the first syllable of the main part. Similarly, the module recognizes
the suffix -ieren as stressed, and hence [[abandonnieren]] /abandɔnˈiːʁən/ "to abandon". The module also knows about
stressed prefixes such as auf-, aus-, über-, etc. and unstressed suffixes as -chen and -lich. Although they don't
change the position of the stress, they have other effects. For example, in [[aufstellen]] /ˈaʊ̯fˌʃtɛlən/ "to set up"
the main part following the stressed prefix gets secondary stress and is treated as word-initial (hence 'st-' is
rendered as /ʃt/). Similarly, in [[Mädchen]] /ˈmɛːtçən/ "girl" the main part is treated as if word-final and hence the
stressed vowel 'ä' is lengthened before a single word-final consonant. In the presence of both a stressed prefix and
suffix, the prefix takes precedence and the suffix gets secondary stress, hence [[ausprobieren]] /ˈaʊ̯spʁoˌbiːʁən/
"to try out".
Use an acute accent on a vowel to override the position of primary stress (in a diphthong, put it over the first
vowel): á é í ó ú ä́ ö́ ǘ ái éi áu ä́u éu. Examples: [[systemisch]] 'systémisch' /zʏsˈteːmɪʃ/ "systemic", [[Migräne]]
'Migrä́ne' /miˈɡʁɛːnə/ "migraine". Use a grave accent to add secondary stress: à è ì ò ù ä̀ ö̀ ǜ ài èi àu ä̀u èu. Examples:
[[Prognose]] 'Prògnóse' /ˌpʁoˈɡnoːzə/ "forecast", [[Milligramm]] 'Milligràmm' /ˈmɪliˌɡʁam/ "milligram" (the primary
stress takes its default position on the first syllable, as it is unmarked).
-------------------- COMPOUNDS ------------------
Use a hyphen (-) to indicate a 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, and each part of the
compound gets its own stress (normally primary stress on the first part and secondary stress on the remaining parts).
Examples: [[Hubschrauber]] 'Hub-schrauber' /ˈhuːpˌʃʁaʊ̯bɐ/ "helicopter", [[Landeplatz]] 'Lande-platz' /ˈlandəˌplat͡s/
"landing place, landing pad".
Use a double hyphen (--) to indicate a word/word boundary in a compound word where one or both of the component words
itself are themselves compounds. Here, the original secondary stresses turn into tertiary stresses (which aren't shown
but are treated internally as stressed) and the primary stress in the second and further components becomes secondary.
An example is [[Hubschrauberlandeplatz]] "helipad" (literally "helicopter landing pad") respelled
'Hub-schrauber--lande-platz' and rendered [ˈhuːpʃʁaʊ̯bɐˌlandəplat͡s]. Comparing this with the above renderings of
[[Hubschrauber]] and [[Landeplatz]], it can be seen that the original primary stress in [[Landeplatz]] becomes
secondary while the original secondary stresses disappear. The loss of secondary stress has no other effect on the
phonology. For example, consider [[Rundflug]] 'Rund-flug' /ˈʁʊntˌfluːk/ "sightseeing flight" (literally "circular
flight"). When combined with [[Hubschrauber]], the result is [[Hubschrauberrundflug]] 'Hub-schrauber--rund-flug'
/ˈhuːpʃʁaʊ̯bɐˌʁʊntfluːk/ "helicopter sightseeing flight", where the last vowel stays long despite (apparently) losing
the stress.
Other examples to demonstrate the use of single and double hyphens in compounds:
* [[Maulwurfshügel]] 'Maul-wurfs--hügel' /maʊ̯lvʊʁfsˌhyːɡəl/ "molehill"
* [[Hubschrauberabsturz]] 'Hub-schrauber--absturz' /ˈhuːpʃʁaʊ̯bɐˌʔapʃtʊʁt͡s/ "helicopter crash"
* [[Aufenthaltsgenehmigung]] 'Aufenthalts-genehmigung' /ˈaʊ̯f(ʔ)ɛnthalt͡sɡəˌneːmɪɡʊŋ/ "residence permit"
* [[Magenschleimhautentzündung]] 'Magen-schleim-haut--entzündung' /ˈmaːɡənʃlaɪ̯mhaʊ̯t(ʔ)ɛntˌt͡sʏndʊŋ/ "gastritis"
(literally "gastric mucosal inflammation")
* [[Kraftfahrzeug-Haftpflichtversicherung]] 'Kraft-fahr-zeug--Haft-pflicht-versicherung'
'ˈkʁaftfaːʁt͡sɔɪ̯kˌhaftp͡flɪçtfɛʁzɪçəʁʊŋ' "motor vehicle liability insurance"
* [[Eierschalensollbruchstellenverursacher]] 'Eier-schalen--soll-bruch-stellen--verursacher'
/ˈaɪ̯ɐʃaːlənˌzɔlbʁʊxʃtɛlənfɛʁˌʔuːʁzaxɐ/ "egg cracker, eggshell breaker" (literally "eggshell breaking point causer")
Explicitly marked stresses using acute and grave accents are *relative* stresses, i.e. they are relative to the
component they are within. To make this clear, consider [[Pilot]] 'Pilót' /piˈloːt/ "pilot". When combined with
[[Hubschrauber]], the result is [[Hubschrauberpilot]] 'Hub-schrauber--pilót' /ˈhupʃʁaʊ̯bɐpiˌloːt/ "helicopter pilot".
Here, the rule of compound stressing specifies that the first component gets primary stress while remaining components
get secondary stress. The primary stress specified here by the acute accent on [[Pilot]] is *relative* to the overall
component stress, and hence it is displayed as secondary stress.
Other examples with explicitly marked stress in compounds:
* [[Ministerpräsidentenkandidatin]] 'Miníster-präsidénten-kandidátin' /miˈnɪstɐpʁɛziˌdɛntənkandiˌdaːtɪn/
"(female) prime minister candidate"
* [[Eisbearbeitungsmaschine]] 'Eis-bearbeitungs--maschíne' /ˈaɪ̯sbəʔaʁbaɪ̯tʊŋsmaˌʃiːnə/ "ice resurfacing machine"
* [[Hochtemperaturreaktor]] 'Hohch-temperatúr-reáktor' /ˈhoːxtɛmpəʁaˌtuːʁʁeˌaktoːʁ/ "high temperature reactor"
* [[Arbeitsbeschaffungsprogramm]] 'Arbeits-beschaffungs--prográmm' /ˈaʁbaɪ̯t͡sbəʃafʊŋspʁoˌɡʁam/ "job creation program"
"helicopter pilot", compounded of [[Hubschrauber]] and [[Pilot]] "pilot". The latter must be respelled 'Pilót' due to the unexpected stress.
The combination [[Hubschrauberpilot]] should correspondingly be respelled 'Hub-schrauber--pilót', rendered as
[ˈhupʃʁaʊ̯bɐpiˌloːt]. Here, the primary stress should be converted to secondary; otherwise the word would
wrongly end up rendered as [ˌhupʃʁaʊ̯bɐpiˈloːt], where the module assumes that since the second word has the
primary stress, other words (including the first one) should have secondary stress. Other similar examples:
[[Hubschrauberabsturz]] "helicopter crash" 'Hub-schrauber--absturz' /ˈhuːpʃʁaʊ̯bɐˌʔapʃtʊʁt͡s/ (the stressed
prefix ab- is automatically recognized) and [[Maulwurfshügel]] "molehill" /ˈmaʊ̯lvʊʁfsˌhyːɡəl/. Occasionally the
double hyphen should be used even when no single hyphens occur. Another example of note is [[Aufenthaltsgenehmigung]]
"residence permit". [[Aufenthalt]] by itself (without respelling) is rendered /ˈaʊ̯f(ʔ)ɛntˌhalt/, i.e. it has
secondary stress. The respelling 'Aufenthalts-genehmigung' is rendered /ˈaʊ̯f(ʔ)ɛnthalt͡sɡəˌneːmɪɡʊŋ/ without the
original secondary stress; the module recognizes the need to remove the secondary stress here. Essentially, if two
words are joined by an ordinary hyphen and one of them has secondary stress due to a stressed prefix, the hyphen
is implicitly "upgraded" to a double hyphen.
Things may get more complex when stresses "bump up" against each other. For example, [[Abhängigkeit]] "dependency"
with no respelling is rendered [ˈapˌhɛŋɪçkaɪ̯t]. In combination as e.g. [[Drogenabhängigkeit]] "drug dependency,
drug addiction" respelled 'Drogen-abhängigkeit', the result is /ˈdʁoːɡənˌʔaphɛŋɪçkaɪ̯t/, which appears correct.
In combination as e.g. [[Alkoholabhängigkeit]] respelled 'Alkohól-abhängigkeit', the result is
/alkoˈhoːlˌʔaphɛŋɪçkaɪ̯t/, which may sound wrong to native ears because of the two stresses bumping up against each
other. The actual pronunciation may be more like /alkoˈhoːl(ʔ)apˌhɛŋɪçkaɪ̯t/ with the secondary stress moving
(respell 'Alkohól-abhä̀ngigkeit') or /alkoˈhoːlʔaphɛŋɪçkaɪ̯t/ with the secondary stress disappearing (respell
'Alkohól-ȧbhängigkeit' where the dot-above suppresses the stress marker but otherwise doesn't change the
phonology).
2. To specify absolute stress
c. NOTE: "Relative" stress refers to how stress is handled specifies the stress on a particular com
Double grave accent to add tertiary stress: ȁ ȅ ȉ ȍ ȕ ä̏ ö̏ ü̏ ȁi ȅi ȁu ä̏u ȅu. Tertiary stress has the same effect on
vowels as secondary stress (e.g. they lengthen in open syllables) but is rendered without a stress mark. Under
normal circumstances, you do not have to explicitly add tertiary stress. Rather, secondary stresses (including
those generated automatically) are automatically converted to tertiary stress in certain circumstances, e.g.
when compounding two words that are already compounds. See the discussion on -- (double hyphen) below.
'h' or ː after a vowel to force it to be long.
Circumflex on a vowel (â ê î ô û ä̂ ö̂ ü̂) to force it to have closed quality.
Breve on a vowel, including a stressed vowel (ă ĕ ĭ ŏ ŭ ä̆ ö̆ ü̆) to force it to have open quality.
Tilde on a vowel or capital N afterwards to indicate nasalization.
For an unstressed 'e', force its quality using schwa (ə) to indicate a schwa, breve (ĕ) to indicate open quality /ɛ/,
circumflex (ê) to indicate closed quality /e/.
. (period) to force a syllable boundary.
- (hyphen) to indicate a 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, and each part of the
compound gets its own stress (primary stress on the first part unless another part has primary stress, secondary
stress on the remaining parts unless stress is explicitly included).
-- (double hyphen) to indicate a word/word boundary in a compound word where one (or both) of the component words
itself is a compound. Here, the original secondary stresses turn into tertiary stresses (not shown) and the
primary stress the second component (and further components) becomes secondary. See discussion below.
< (less-than) to indicate a prefix/word or prefix/prefix boundary; similar to - for word/word boundary, but the
prefix before the < sign will be unstressed.
> (greater-than) to indicate a word/suffix or suffix/suffix boundary; similar to - for word/word boundary, but the
suffix after the > sign will be unstressed.
+ (plus) is the opposite of -; it forces a prefix/word, word/word or word/suffix 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.
̣ (dot under) on any vowel in a word or component to prevent it from getting any stress.
̯ (inverted breve under) to indicate a non-syllabic vowel. Most common uses: i̯ in words like [[Familie]]
respelled 'Famíli̯e'; o̯ in French-derived words like [[soigniert]] respelled 'so̯anjiert' (-iert automatically gets
primary stress); occasionally y̯ in words like [[Ichthyologie]] respelled 'Ichthy̯ologie' (-ie automatically gets
primary stress). There is also u̯ but it's mostly unnecessary as a 'u' directly followed by another vowel by
default becomes non-syllabic. Finally, the generated phonemic notation includes /aɪ̯/ for spelled 'ei' and 'ai';
/ɔɪ̯/ for spelled 'eu' and 'äu'; and /aʊ̯/ for spelled 'au'; and the generated phonetic notation includes [ɐ̯] for
vocalized /ʁ/ (i.e. written 'r' in a syllable coda). However, you rarely if ever need to type these symbols
explicitly.
Notes:
1. Doubled consonants, as well as digraphs/trigraphs etc. like 'ch', 'ng', 'tz', 'sch', 'tsch', etc. cause a
preceding vowel to be short and open (/ɛ ɪ ɔ ʊ œ ʏ/) unless lengthened with h or ː.
2. With occasional exceptions, a vowel before a single consonant (including at the end of a word or component)
is closed (/e i o u ø y/), and long if stressed (primary or secondary).
3. The vowel 'e' is rendered by default as schwa (/ə/) in the following circumstances:
a. The prefixes 'ge-', 'be-' are recognized specially and rendered with a schwa and without stress. This doesn't
apply if:
i. The 'e' is respelled with an accent, e.g. 'Génitiv' for [[Genitiv]] "genitive" or 'géstern' for [[gestern]]
"yesterday".
ii. A + is placed at the putative prefix boundary. Hence [[Geograf]] "geographer" could be respelled 'Ge+ográf'
to prevent 'Ge' from being interpreted as a prefix.
iii. The cluster following the 'ge-' or 'be-' cannot be the start of a German word, e.g. [[bellen]] "to bark"
('ll' cannot start a word) or [[bengalisch]] "Bengal" ('ng' cannot start a word).
a. If there is a following stress in the word, only in an internal (non-initial) open unstressed syllable (i.e.
followed by only a single consonant) when 'r' follows, as in Temp̱e̱ratur, Gene̱ralität, Souve̱ränität, Hete̱rogenität,
degene̱rieren, where the underlined vowels are by default rendered as a schwa. Other cases with schwa like
[[Sozietät]] or [[Pietät]] need to be respelled with a schwa, e.g. 'Soziǝtät', 'Pìǝtät'.
b. If there is no following stress, any 'e' word-finally or followed by consonants that might form part of an
inflectional ending is rendered as a schwa, e.g. Lage̱, zuminde̱ste̱ns, verschiede̱ne̱n, verwende̱t. Examples where
this does not happen are Late̱x, Ahme̱d, Bize̱ps, Borre̱tsch, Brege̱nz, which would be rendered by default with /ɛ/ or
/e/. Cases like [[Achilles]] and [[Agens]] that have /ɛ/ but end in what looks like an inflectional ending should
be respelled with ĕ.
4. Obstruents 'b' 'd' 'g' 'v' 'ʒ' are normally rendered as voiceless /p t k f ʃ/ at the end of a word or syllable.
To cause them to be voiced, one way is to move the syllable boundary before the consonant by inserting a . before
the consonant. If that isn't appropriate, add a * after the sound, as in 'b*', 'd*', 'z*', etc.
5. 'v' is normally rendered as underlying /v/ (which becomes /f/ at the end of a word or syllable). Words like [[vier]],
[[viel]], [[Vater]], etc. need respelling using 'f'. Note that prefixes ver-, vor-, voraus-, vorher-, etc. are
recognized specially.
6. French-derived words often need respelling and may have sounds in them that don't have standard spellings in
German. For example, [[Orange]] can be spelled 'Orã́ʒe' or 'OráNʒe'; use a tilde or a following capital N to
indicate a nasal vowel, and use a 'ʒ' character to render the sound /ʒ/.
7. Rendering of 'ch' using ich-laut /ç/ or ach-laut /x/ is automatic. To force one or the other, use 'ç' explicitly
(as in 'Açilles-ferse' for one pronunciation of [[Achillesferse]] "Achilles heel") or 'x' explicitly (as in
'X*uzpe' for [[Chuzpe]] "chutzpah").
8. Vowels 'i' and 'u' in hiatus (i.e. directly before another vowel) are normally converted into glides, i.e. /i̯ u̯/,
as in [[effizient]] (no respelling needed as '-ent' is recognized as a stressed suffix), [[Antigua]] (respelled
'Antíguah'). To preven this, add a '.' between the vowels to force a syllable boundary, as in [[aktualisieren]]
'àktu.alisieren'. An exception to the glide conversion is the digraph 'ie'; to force glide conversion, as in
[[Familie]], use 'i̯' explicitly (respelled 'Famíli̯e'). Occasionally the ̯ symbol needs to be added to other vowels,
e.g. in [[Ichthyologie]] respelled 'Ichthy̯ologie' (note that '-ie' is a recognized stressed suffix) and
[[soigniert]] respelled 'so̯anjiert' ('-iert' is a recognized stressed suffix).
FIXME:
1. Implement < and > which works like - but don't trigger secondary stress (< after a prefix, > before a suffix).
2. Implement <!, -! which work with < and - but suppress the vowel-initial glottal stop; <?, -? which work similarly
but allow for optional glottal stop.
3. Implement prefix/suffix stripping; don't do it if explicit syllable boundary in cluster after prefix, or if no
vowel in main, or if impossible prefix/suffix onset/offset.
4. Automatically support -ge-, -zu- after stressed verbal prefixes.
5. Figure out how to support stacked suffixes like -barkeit, -samkeit, -lichkeit, -schaftlich, -licherweise. Perhaps
there is a small enough set of common stacked suffixes to just list them all.
6. Finish entering prefixes and suffixes.
7. Add default stresses (primary stress on first syllable of first stressed component, etc.).
8. Handle inflectional suffixes: adjectival -e, -en, -em, -er, -es, also after adjectival -er, -st; nominal -(e)s,
-(e)n; verbal -e, -(e)st, -(e)t, -(e)n, -(e)te, -(e)tst, -(e)tet, -(e)ten.
9. Ignore final period/question mark/exclamation point.
10. Implement nasal vowels.
11. Implement underscore to prevent assimilation/interpretation as a multigraph.
12. Implement [b] [d] [g] [z] [v] [s] [x].
13. Implement dot-under to prevent stress.
14. Implement dot-over on a vowel to prevent a given autogenerated stress mark from being displayed.
15. Check allowed onsets with prefixes.
16. Implement allowed offsets and check with suffixes.
17. Implement 'style' ala Spanish pronun to handle standard vs. northern/Eastern vs. southern:
e.g. [[berufsunfähig]]:
/bəˈʁuːfs(ʔ)ʊnˌfɛːɪç/ {{qualifier|standard; used naturally in western Germany and Switzerland}}
/-ʔʊnˌfeːɪç/ {{qualifier|overall more common; particularly northern and eastern regions}}
/-ʔʊnˌfɛːɪk/ {{qualifier|common form in southern Germany, Austria, and Switzerland}}
e.g. [[aufrichtig]]:
/ˈaʊf.ʁɪç.tɪç/ {{qualifier|standard}}
/ˈaʊf.ʁɪç.tɪk/ {{qualifier|common form in southern Germany, Austria, and Switzerland}}
e.g. [[Universität]]:
/ˌuni.vɛʁ.ziˈtɛːt/ {{qualifier|standard; used naturally in western Germany and Switzerland}}
/ˌuni.vɛʁ.ziˈteːt/ {{qualifier|overall more common; particularly northern and eastern regions}}
18. Implement splitting prefix/suffix pronun for -sam, with two pronunciations.
19. n before g/k in the same syllable should be ŋ. Sometimes also across syllables, cf. [[Ingrid]].
20. Written 'ts' in the same syllable should be rendered with a tie, e.g. [[aufwärts]], [[Aufenhaltsgenehmigung]].
[[Botsuana]] is tricky as it normally would have syllable division 't.s', but maybe we should special-case it
so we get /bɔˈt͡su̯aːna/. Other examples: [[enträtseln]], [[Fietse]], [[Lotse]], [[Mitsubishi]], [[Rätsel]],
[[Hatsa]], [[Tsatsiki]], [[Whatsapp]]. In [[Outsider]] and [[Outsourcing]], the 't' and 's' are pronounced
separately, respelled 'Aut-s*aider' and 'Aut-s*ŏhßing' (or similar).
21. Implement handling of written 'y'.
22. Implement double hyphen and conversion of secondary to tertiary accents.
23. Handle unstressed words like [[und]] and [[von]] correctly.
24. Implement optional glottal stops when the following syllable isn't stressed (but only after a consonant; cf.
[[wiederentdecken]] ˈviːdɐʔɛntˌdɛkən).
25. Use x* etc. to get EXPLICIT_X etc. instead of [x], so that [...] can be used after a word to indicate word
properties.
26. Handle prefixes/suffixes/interfixes indicated with initial and/or final hyphen.
27. t-s- should render as t͡s e.g. [[Gleichheitszeichen]] respelled 'Gleichheit-s-zeichen' and [[Aufenthaltstitel]]
respelled 'Aufenthalt-s-titel'.
28. Need syllable dividers at component boundaries before unstressed syllables.
29. Open syllables with secondary stress get close but not lengthened vowel if there is a following primary stress
within the component bounadry; cf. [[iterativ]] 'ìtêratív' [ˌiteʁaˈtiːf], [[Lethargie]] 'Lèthargie' [ˌletaʁˈɡiː].
Across a component bounadry this doesn't apply, so that e.g. [[hyperaktiv]] 'hỳper-áktihv' would be
[ˌhyːpɐˈʔaktiːf]; if we need short /y/, either make it unstressed, e.g. 'hyper<aktihv' or use *, e.g.
'hỳ*per-áktiv'.
30. Use [vf] after a word for "verb form" to get verbal endings -st, -t, -tet etc. recognized. Expand this to handle
all inflectional endings.
31. Support non-initial capital O for o̯, non-initial N for nasal vowel including after lengthening h, digraphs eI and
oU for /ɛɪ̯/ and /ɔʊ̯/.
32. Nasal vowels should be long when stressed, and use the phonemes ã ɛ̃ õ œ̃ per Wikipedia.
33. Remove primary stress from a single-syllable word.
34. -ik- in the middle of a word should have short 'i', e.g. [[Musikerin]]; not sure if also applies when stress
follows. Cf. [[Abdikation]] /ˌapdikaˈt͡si̯oːn/, [[Partikel]] /paʁˈtɪkəl/ or also /paʁˈtiːkəl/, [[Affrikate]]
/ˌafʁiˈkaːtə/, [[Afrika]] /ˈaːfʁika/ or /ˈafʁika/, [[afrikaans]] /ˌafʁiˈkaːns/, [[Agnostiker]] /aˈɡnɔstɪkɐ/,
[[Agrikultur]] /ˌaɡʁikʊlˈtuːʁ/, [[Akademikerin]] /akaˈdeːmɪkəʁɪn/, [[Silikat]] /ziliˈkaːt/, [[Amerika]]
/aˈmeːʁika/, [[amikal]] /amiˈkaːl/, [[Anabolikum]] /anaˈboːlikʊm/, [[Syndikalismus]] /zʏndikaˈlɪsmʊs/,
[[Angelika]] /aŋˈɡeːlika/, [[Anglikaner]] /aŋɡliˈkaːnɐ/, [[Antibiotikum]] /antiˈbi̯oːtikʊm/, [[Antipyretikum]]
/antipyˈʁeːtikʊm/, [[apikal]] /apiˈkaːl/, [[appendikuliert]] /apɛndikuˈliːʁt/, [[Applikation]] /aplikaˈt͡si̯oːn/,
[[Aprikose]] /ˌapʁiˈkoːzə/, [[Olympionikin]] /olʏmpi̯oˈniːkɪn/, [[Tsatsiki]] /t͡saˈt͡siːki/, [[Artikel]]
/ˌaʁˈtiːkəl/ or /ˌaʁˈtɪkəl/, [[Batiken]] /ˈbaːtɪkən/. Seems to apply only to unstressed '-ik-' followed by 'e' +
no stress.
35. 'h' between vowels should be lengthening only if no stress follows and the following vowel isn't a or o, and if
followed by i or u, that vowel should not be word-final. (DONE)
36. Re-parse prefix/suffix respellings for <, e.g. auseinander-.
37. Reimplement prefix-type restrictions using a finite state machine and handle secondary stress appropriately.
38. ks should divide .ks but shorten preceding vowels. (DONE)
39. Implement component_like_suffixes.
40. Make sure [[kohlenhydratreich]] respelled 'kohlen-hydrȁt>reich' works.
41. Redo multicomponent handling according to recent changes whereby acute and grave indicate relative stress rather
than absolute stress; absolute stress can be specified using ˈ and ˌ or ' (single quote) and , (comma). Component
stress is specified using * (primary stress) or ** (secondary stress) at the beginning of the component.
42. Prefix standing alone as a word or component should be recognized and respelled appropriately; cf. words like
[[vorüber]], [[auseinander]], [[ab]], [[um]].

------------------------- Recognized prefixes -------------------------
--[=[
The following contains prefixes to be recognized specially, segmented off automatically and respelled appropriately.
The format of each entry is {PREFIX, RESPELLING, PROPS...} where PREFIX is the actual spelling of the prefix (without
any stress marks), RESPELLING is the appropriate phonemic respelling, spelled as if the prefix were a word by itself
(with appropriate acute and grave accents marking primary and secondary stress). PROPS are optional named properties;
see below. Order of the entries is important as they are checked in order. In particular, B must follow A if B is a
prefix of A. For example, "her" must follow "heraus", "herbei", "herüber", etc. and "un" must follow "unter".
The following named properties are currently recognized:
* 'restriction': Place additional restrictions on when the prefix can occur. Value is either a regex that must match
the part of the word to the right of the prefix, or a list of such regexes, where one of them must match in the
same fashion. An example is "emp", which has a restriction so that it is only recognized in the form "empf-", i.e.
where the rest of the word begins with an f.
* 'prefixtype': Override the autodetected type of prefix, one of "stressed", "unstressed", "unstressed-zu" or "un".
The types "stressed" and "unstressed" are autodetected and don't normally need to be given, but the other two must
be given using 'prefixtype' whenever they are applicable.
* 'secstress': If the prefix is stressed, i.e. its respelling has an acute accent, this should specify the prefix --
in its original form, not respelled form -- with the appropriate vowel given a grave accent. This can be omitted
if the secondary stress goes on the first vowel. This is used so that the user can put secondary stress on a
prefix (whether or not explicitly sectioned off using '<') and still have it recognized and respelled
appropriately. An example is [[unkalkulierbar]], respelled 'ùnkalkulierbar', which generates /ˌʊnkalkuˈliːʁbaːʁ/.
Note for example that the 'n' shows up as /n/ not /ŋ/ before 'k', and 'u' shows up as /ʊ/ not /u/, which indicates
that 'ùn-' is correctly sectioned off as a prefix and given a respelling of 'ùnn-'.
* 'not_with_following_primary_stress': Do not recognize this prefix if there is a primary stress later on in the
word. This is used with prefixes such as 'ab-', 'an-', 'her-', 'mit-', 'ur-' that frequently form non-prefix parts
of foreign-origin words (e.g. [[abundant]], [[Animation]], [[hereditär]], [[mitigieren]], [[Urbanisierung]]).
This is a heuristic as most foreign-origin words have non-initial stress; but it produces some false positives
e.g. [[Abenteuer]], [[Annika]], [[Herkules]], [[uruguayisch]] (which need respelling like 'Ab+enteuer' with '+'
to indicate no prefix boundary or alternatively 'Ábenteuer' with explicit stress) and occasional false negatives
e.g. [[abalienieren]], [[anhand]] (which need respelling using '<', like 'an<hand' or 'àb<ali̯enieren'; the latter
also puts secondary stress on the prefix, which will be propagated onto the respelling 'àbb', and uses 'i̯' to get
a glide rather than 'ie' being interpreted as a long vowel).
Some prefixes can be both stressed and unstressed, e.g. durch-, unter-, über-, wieder-. For some, e.g. miss- and
wider-, there are systematic alternations in stress: unstressed when functioning as a verbal prefix followed by an
initial-stressed verb, stressed otherwise. This is too complex and unpredictable for us to handle, so we treat all
these prefixes as stressed. Respell using < when unstressed, e.g. 'umfahren' "to knock down with a vehicle",
'um<fahren' "to drive around, to bypass".

------------------------- Recognized "component-like" suffixes -------------------------
--[=[
The following contains suffixes that maintain their stress after a stressed syllable, as in [[handfest]], [[reißfest]],
and "steal" the secondary stress, as in [[albtraumhaft]] /ˈalptʁaʊ̯mˌhaft/. The format of each entry is approximately
the same as for prefixes above. The differences are:
* Order matters, as for prefixes, but in this case the rule is that B must follow A if B is a suffix of A, e.g. "bar"
must follow "ierbar" and "haft" must follow "schaft".
* The respelling can be a list of possible pronunciations, in which case multiple pronunciations are produced on
output. This is used e.g. for "-sam", which has two possible pronunciations, with the vowel long or short.
(FIXME: We don't actually support this yet.)
* There is an additional named property 'pos' that is intended to specify the resulting part of speech (a string, one
of 'n' = noun, 'v' = verb, 'a' = adjective, 'b' = adverb, or a list of such strings). This is currently underused and
may be deleted.
* The named properties 'prefixtype' and 'not_with_following_primary_stress' do not exist.
* The named property 'restriction' works as for prefixes except that it matches the part *before* the suffix. For
example, "erweise" is restricted to follow a consonant.

------------------------- Recognized regular-stressing suffixes -------------------------
--[=[
The following contains suffixes that have regular suffix stress. That is, if stressed with secondary stress, they take
secondary stress only when the preceding syllable has no stress and there is no preceding secondary stress, e.g. for
-lein in [[Fingerlein]], [[Schwesterlein]] or [[Müllerlein]] /ˈmʏlɐˌlaɪ̯n/. In most words, this condition doesn't hold,
and so e.g. -lein has no stress, e.g. [[Äuglein]] /ˈɔɪ̯klaɪ̯n/ or [[Bäumlein]] /ˈbɔɪ̯mlaɪ̯n/. This includes secondary
stress of the type found in [[Ecklädlein]] /ˈɛkˌlɛːtlaɪn/, [[Hofkirchlein]] /ˈhoːfˌkɪʁçlaɪ̯n/, [[Apfelbäumlein]]
/ˈap͡fəlˌbɔɪ̯mlaɪ̯n/. This is contrary to the behavior of compounds-of-compounds like [[Hubschrauberlandeplatz]] and
[[Maulwurfshügel]] described above; by that rule, we'd expect #/ˈap͡fəlbɔɪ̯mˌlaɪ̯n/ or similar. Cf. similarly
[[Abhängigkeit]] /ˈapˌhɛŋɪçkaɪ̯t/.
The format of each entry is as for component-like suffixes above.
Note that vowel-initial suffixes are joined phonemically directly onto the preceding part, without any sort of morpheme
boundary. As a result, vowel-initial suffixes that bear no stress and require no respelling, such as "ung" and "isch",
do not need to be given here.

-- (2) Prefix and suffix splitting, with the addition of ⁀ or ‿ at boundaries of words, components, prefixes and

------------------------- 'y' -------------------------
--[=[
In general, we convert 'y' to either 'ü', 'i', 'I' or 'j'. Do this before handling diphthongs because the resulting
'i' may be in the combination 'ai' or 'ei', which needs to be handled as a diphthong.
1. Accented 'y' always becomes 'ü'.
2. Initial 'y' followed by a vowel becomes 'j', as in [[New York]] respelled 'Nju Yórk' /njuː ˈjɔrk/, [[Yacht]]
/jaxt/, [[Yak]] /jak/, [[Yang]] /jaŋ/, [[Yannick]] /ˈjanɪk/, [[Yen]] /jɛn/, [[Yersiniose]] /jɛʁziˈni̯oːzə/, [[Yeti]]
/ˈjeːti/, [[Yobibyte]] respelled 'Yóbibàit' /ˈjoːbiˌbaɪ̯t/, [[Yoga]] /ˈjoːɡa/, [[Yoni]] /ˈjoːni/, [[Yottabyte]]
respelled 'Yóttabàit' /ˈjɔtaˌbaɪ̯t/, [[Yuppie]] respelled 'Yuppi' /ˈjʊpi/.
3. Initial 'y' not followed by a vowel becomes 'ü', as in [[Ylid]] /yˈliːt/, [[Yperit]] /ypəˈʁiːt/, [[Ypern]]
/ˈyːpɐn/, [[Ypsilon]] /ˈʏpsilɔn/, [[Ytterbium]] /ʏˈtɛʁbi̯ʊm/, [[Yttererde]] /ˈʏtɐˌʔeːɐ̯də/, [[Yttrium]] /ˈʏtʁiʊm/.
Some words of this form need respelling: [[Ybbsitz]] respelled 'Ibbsitz', [[Ysop]] respelled 'Isop', [[Yspertal]]
respelled 'Isper-tal', [[Yvonne]] respelled 'Ivónn'.
4. Final 'y' after a consonant becomes 'i', as in [[Hobby]] /ˈhɔbi/, [[Body]] respelled 'Boddy' /ˈbɔdi/,
[[Stransky]] /ˈʃtʀanski/, [[Monopoly]] /moˈnoːpoli/, [[Whisky]] /ˈwɪski/, [[Sony]] /ˈzoːni/, etc.
5. Other 'y' after a consonant becomes 'ü', as in [[symmetrisch]] /zʏˈmeːtʁɪʃ/, [[Pyramide]] /ˌpyʁaˈmiːdə/,
[[Psychologie]] /psyçoloˈɡiː/, [[Acryl]] /aˈkʁyːl/, [[Aerodynamik]] /aeʁodyˈnaːmɪk/, [[Ägypten]] /ˌɛˈɡʏptn̩/,
[[analytisch]] /anaˈlyːtɪʃ/, [[Beryllium]] /beˈʁʏli̯ʊm/, etc. Also between a consonant and a vowel, e.g. [[Cyan]]
/t͡syˈaːn/, [[Kryometer]] /kʁyoˈmeːtɐ/, [[Dryade]] /dʁyˈaːdə/, [[Eukaryot]] /ɔɪ̯kaʁyˈoːt/, [[euryök]] /ɔɪ̯ʁyˈʔøːk/,
[[Harpyie]] /haʁˈpyːjə/, [[Amblyopie]] /amblyoˈpiː/, [[Myon]] /ˈmyːɔn/, [[Karyatide]] /kaʁyaˈtiːdə/. Some words of
the latter form need respelling, e.g. [[Myanmar]] respelled 'Miánmahr' /ˈmi̯anmaːɐ̯/, [[Libyen]] respelled 'Libien'
/ˈliːbi̯ən/, [[Magyar]] respelled 'Madjáhr' /maˈdjaːɐ̯/, [[Polyamorie]] respelled 'Poly-amoríe' /ˌpoːliʔamoˈʁiː/,
[[Polyester]] respelled 'Poliéster' /poˈli̯ɛstɐ/, [[Prokaryot]] respelled 'Prokary̯ót' /pʁokaˈʁy̯oːt/, [[Rallye]]
respelled 'Rally' /ˈʁali/ or 'Relly' /ˈʁɛli/, [[Canyon]] respelled 'Kenjen' /ˈkɛnjən/, [[Babyöl]] respelled
'Beby-öl' /ˈbeːbiˌʔøːl/, [[Ichthyologie]] respelled 'Ichthy̯ologie' /ɪçty̯oloˈɡiː/, etc. More rarely, some words of
the former form also need respelling, e.g. [[Calypso]] respelled 'Kalípso' /kaˈlɪpso/.
6. In the sequences 'ay', 'oy' not followed by a vowel, or followed by e/i/u and no stress follows, the 'y'
becomes 'I', e.g. [[Bayern]] /ˈbaɪ̯ɐn/, [[Hoyerswerda]] respelled 'Hoyers-*verda' /hɔɪ̯ɐsˈvɛʁda/, [[Mayer]] /ˈmaɪ̯ɐ/,
[[Paraguay]] /ˈpaːʁaɡvaɪ̯/ or /ˈpaʁaɡvaɪ̯/ or /paʁaˈɡu̯aɪ̯/, [[Uraguayer]] /ˈuːʁuɡvaɪ̯ɐ/ or /ˈʊʁuɡvaɪ̯ɐ/ or /ˌuʁuˈɡu̯aɪ̯ɐ/,
[[Payerbach]] respelled 'Payer-bach', [[Bayreuth]] /baɪ̯ˈʁɔʏ̯t/, [[bayrisch]] /ˈbaɪ̯ʁɪʃ/, [[Boykott]] /ˌbɔɪ̯ˈkɔt/,
[[Malaysia]] /maˈlaɪ̯zi̯a/, [[Maybach]] /ˈmaɪbax/.
7. In the sequence 'ey' in the same circumstances as the previous entry, the 'y' becomes 'i', e.g. [[Meyer]]
/ˈmaɪ̯ɐ/, [[Leyermann]] respelled 'Leyer-mann' /ˈlaɪ̯ɐˌman/, [[Speyer]] /ˈʃpaɪ̯ɐ/, [[Leyen]] /ˈlaɪ̯ən/, obsolete
spellings like [[beyde]] for [[beide]] or [[dabey]] for [[dabei]] or [[meyn]] for [[mein]], [[Geysir]] /ɡaɪ̯ˈziːʁ/.
8. Other 'y' after vowels becomes 'j', e.g. [[Alija]] /aˈlija/, [[Ayatollah]] /ˌajaˈtɔla/, [[Ayurveda]]
/ajʊʁˈveːda/, [[Cayenne]] respelled 'Kayén' /kaˈjɛn/, [[Chaya]] respelled 'Tschaya' /ˈt͡ʃaːja/, [[Cherimoya]]
respelled 'Tscherimoya' /t͡ʃeʁiˈmoːja/, [[flamboyant]] respelled 'flãbOayant' /flɑ̃bo̯aˈjant/, [[Guyana]] /ɡuˈjaːna/,
[[Französisch-Guayana]] /[fʁanˌt͡søːzɪʃ ɡuaˈjaːna/, [[Himalaya]] /hiˈmaːlaja/ or /himaˈlaːja/, [[Larmoyanz]]
respelled 'LarmOayanz' /laʁmo̯aˈjant͡s/, [[loyal]] /loˈjaːl/, [[Malayalam]] /malaˈjaːlam/ or /malajaˈlaːm/, [[Maya]]
/ˈmaːja/, [[Mayo]] /ˈmaːjo/, [[oktroyieren]] respelled 'oktrOayieren' /ɔktʁo̯aˈjiːʁən/, [[Oriya]] /oˈʁiːja/,
[[Papaya]] /paˈpaːja/, [[Toyota]] /toˈjoːta/.

-- 2. Before the stress, 'e' in a closed syllable is never a schwa.
-- 2. Initial unstressed 'e' as in [[Elektrizität]] is never a schwa.
-- 3. Before the stress, 'e' in the first syllable is not normally a schwa, cf. [[Negativität]], [[Benefaktiv]].
-- 4. Before the stress, 'e' in hiatus is not a schwa, cf. [[Idealisierung]].
-- 5. In open non-initial syllables before the stress, it *MAY* be a schwa, esp. before 'r', e.g.
-- [[Temperatur]] with /ə/; [[Generalität]] with /ə/; [[Souveränität]] with /ə/; [[Heterogenität]] with /ə/ before 'r' but /e/ later on;
-- same for [[Kanzerogenität]]; but [[Immaterialität]] with /e/; [[Benediktiner]] optionally with /ə/ in second
-- syllable; [[Pietät]] with /ə/; [[Sozietät]] with /ə/ but [[Varietät]] with /e/, [[abalienieren]] with /e/;

-- [[acetylieren]] with /e/; [[akkreditieren]] with /e/; [[ameliorieren]] with /e/; [[anästhesieren]] with /e/;
-- [[degenerieren]] with /e/ /e/ /ə/; etc.
-- 6. After the stress, 'e' is more likely to be schwa, e.g. [[zumindestens]] /t͡suˈmɪndəstəns/. But not always,
-- e.g. [[Latex]] [ˈlaːtɛks] (dewikt); [[Index]] /ɪndɛks/; [[Alex]] /ˈalɛks/; [[Achilles]] [aˈxɪlɛs] (dewikt);
-- [[Adjektiv]] /ˈa.djɛkˌtiːf/ or /ˈat.jɛk-/; [[Adstringens]] [atˈstrɪŋɡɛns]; [[Adverb]] /ˈat.vɛʁp/
