1.Purpose of this reference page
This is a cross-level reference to German vowels.
It mainly answers:
Which vowels does German have?
Which are long and which are short?
How do length and vowel quality interact?
Which spellings are typical?
What happens with e, r, and umlauts?
Which minimal pairs matter most?
The examples are based on broadly intelligible standard pronunciation; relevant regional variation is noted where useful.
2.Core idea: length and quality
German vowels often differ along two dimensions:
length
→ long vs short
quality
→ closer / tenser vs more open / laxer
Compare:
bieten /ˈbiːtən/
bitten /ˈbɪtən/
The contrast is not only duration; vowel quality changes as well.
3.IPA on this page
Phonemic transcription is shown between slashes:
/iː/
/ɪ/
/eː/
/ɛ/
The symbol:
ː
marks a long sound.
Example:
/iː/
= long vowel.
4.Core monophthongs: overview
Compact overview:
| Area | long | short |
|---|---|---|
| i | /iː/ | /ɪ/ |
| e | /eː/ | /ɛ/ |
| ä | /ɛː/ | /ɛ/ |
| a | /aː/ | /a/ |
| o | /oː/ | /ɔ/ |
| u | /uː/ | /ʊ/ |
| ü | /yː/ | /ʏ/ |
| ö | /øː/ | /œ/ |
Also important:
/ə/ schwa
/ɐ/ vocalised r
5./iː/: long i vowel
/iː/ examples:
Liebe /ˈliːbə/
bieten /ˈbiːtən/
Ziel /tsiːl/
ihm /iːm/
Typical spellings:
ie
i
ih
ieh
A very common pattern is:
ie → /iː/
6./ɪ/: short i vowel
Examples:
bitten /ˈbɪtən/
mit /mɪt/
Sinn /zɪn/
Kind /kɪnt/
It is shorter and more open than /iː/.
7./iː/ vs /ɪ/
Important contrast:
bieten /ˈbiːtən/
bitten /ˈbɪtən/
Miete /ˈmiːtə/
Mitte /ˈmɪtə/
Remember:
long i
→ longer + closer
short i
→ shorter + more open
8./eː/: long close e vowel
Examples:
See /zeː/
leben /ˈleːbən/
gehen /ˈɡeːən/
zehn /tseːn/
This vowel is relatively close and long.
9./ɛ/: short open e vowel
Examples:
Bett /bɛt/
kennen /ˈkɛnən/
hell /hɛl/
setzen /ˈzɛtsən/
It is more open than /eː/.
10./eː/ vs /ɛ/
Compare:
Beet /beːt/
Bett /bɛt/
Both change:
length
+
degree of openness
11./ɛː/: long ä vowel
Long ä is traditionally represented as:
/ɛː/
Examples:
spät /ʃpɛːt/
Käse /ˈkɛːzə/
wählen /ˈvɛːlən/
In many standard varieties, this vowel approaches /eː/ or partly merges with it.
12.Long ä: variation
In words such as:
Käse
spät
zählen
depending on standard variety and speaker, one may hear:
/ɛː/
or a realisation closer to:
/eː/
For learners:
Both standard-like realisations occur; consistency and intelligibility are more important than forcing one exact variant.
13.Short ä
Short ä is generally pronounced like short e:
/ɛ/
Examples:
Männer /ˈmɛnɐ/
Hände /ˈhɛndə/
kälter /ˈkɛltɐ/
There is normally no important phonetic contrast between short e and short ä.
14./aː/: long a vowel
Examples:
Tag /taːk/
Saal /zaːl/
fahren /ˈfaːʁən/
Zahn /tsaːn/
Unlike many other vowel pairs, the quality difference between long and short a is relatively small.
15./a/: short a vowel
Examples:
Mann /man/
Stadt /ʃtat/
kann /kan/
lassen /ˈlasən/
The main contrast with /aː/ is usually duration.
16./aː/ vs /a/
Compare:
Staat /ʃtaːt/
Stadt /ʃtat/
With a, duration is especially important because the quality difference is smaller than in:
/iː/ – /ɪ/
/uː/ – /ʊ/
/oː/ – /ɔ/
17./oː/: long close o vowel
Examples:
Ofen /ˈoːfən/
Boot /boːt/
Sohn /zoːn/
rot /ʁoːt/
The vowel is long and relatively close.
18./ɔ/: short open o vowel
Examples:
offen /ˈɔfən/
Sonne /ˈzɔnə/
Kopf /kɔpf/
kommen /ˈkɔmən/
It is shorter and more open than /oː/.
19./oː/ vs /ɔ/
Compare:
Ofen /ˈoːfən/
offen /ˈɔfən/
Difference:
/oː/
→ longer + closer
/ɔ/
→ shorter + more open
20./uː/: long u vowel
Examples:
gut /ɡuːt/
Schule /ˈʃuːlə/
Uhr /uːɐ̯/
Buch /buːx/
The vowel is long, close, and rounded.
21./ʊ/: short u vowel
Examples:
Mutter /ˈmʊtɐ/
Hund /hʊnt/
muss /mʊs/
Kunst /kʊnst/
It is shorter and more open than /uː/.
22./uː/ vs /ʊ/
Compare:
Mut /muːt/
Mutter /ˈmʊtɐ/
A common learner issue is:
pronouncing short /ʊ/ like long /uː/
This can make the contrast sound unnatural and may occasionally blur lexical distinctions.
23./yː/: long ü vowel
Examples:
Tür /tyːɐ̯/
grün /ɡʁyːn/
fühlen /ˈfyːlən/
über /ˈyːbɐ/
Basic articulation:
tongue roughly as for /iː/
+
rounded lips
24./ʏ/: short ü vowel
Examples:
fünf /fʏnf/
müssen /ˈmʏsən/
Glück /ɡlʏk/
dünn /dʏn/
It is shorter and more open than /yː/.
25./yː/ vs /ʏ/
Compare:
fühlen /ˈfyːlən/
füllen /ˈfʏlən/
Both vowels are front and rounded.
Contrast:
/yː/
→ long + close
/ʏ/
→ short + more open
26./øː/: long ö vowel
Examples:
schön /ʃøːn/
Höhe /ˈhøːə/
lösen /ˈløːzən/
Öl /øːl/
Articulation:
tongue roughly as for /eː/
+
rounded lips
27./œ/: short ö vowel
Examples:
können /ˈkœnən/
Hölle /ˈhœlə/
zwölf /tsvœlf/
Köpfe /ˈkœpfə/
It is shorter and more open than /øː/.
28./øː/ vs /œ/
Compare:
Höhle /ˈhøːlə/
Hölle /ˈhœlə/
Contrast:
/øː/
→ long + close
/œ/
→ short + more open
29.Umlaut vowels as a system
The three umlaut letters:
ä
ö
ü
systematically correspond to:
a → ä
o → ö
u → ü
Common word-family patterns include:
Mann → Männer
Buch → Bücher
groß → größer
30./ə/: schwa
Schwa is an unstressed central vowel:
/ə/
It commonly appears in unstressed syllables:
bitte /ˈbɪtə/
Name /ˈnaːmə/
leben /ˈleːbən/
machen /ˈmaxən/
Schwa is short, weak, and never carries primary stress.
31.Schwa in -e
Unstressed word-final -e is very often pronounced /ə/:
Bitte /ˈbɪtə/
Schule /ˈʃuːlə/
Frage /ˈfʁaːɡə/
Do not pronounce it like full:
/eː/
32.Schwa in -en
The ending -en is often realised in careful speech approximately as:
/ən/
Examples:
machen /ˈmaxən/
leben /ˈleːbən/
In natural speech, the schwa may be reduced or deleted.
33.Schwa deletion
In spoken standard German, /ə/ may disappear in endings.
Simplified examples:
haben /ˈhaːbən/
→ often reduced
reden /ˈʁeːdən/
→ often reduced
Important:
The exact reduction depends on phonetic environment, speech rate, and region.
34./ɐ/: vocalised r
After a vowel or in unstressed -er, r is vocalised in many standard pronunciation varieties.
Typical examples:
Lehrer /ˈleːʁɐ/
besser /ˈbɛsɐ/
Kinder /ˈkɪndɐ/
The result resembles a central vowel:
/ɐ/
35.Word-final -er
Very commonly:
-er → /ɐ/
Examples:
Mutter /ˈmʊtɐ/
Vater /ˈfaːtɐ/
Wasser /ˈvasɐ/
A strong rolled or uvular r is not required word-finally.
36.Vowel + r
After a long vowel, r is often vocalised.
Examples:
Tier /tiːɐ̯/
Tür /tyːɐ̯/
Uhr /uːɐ̯/
mehr /meːɐ̯/
The exact realisation varies regionally.
37.Diphthongs: overview
The three core German diphthongs are:
/aɪ̯/
/aʊ̯/
/ɔʏ̯/
Typical spellings:
ei, ai, ey, ay → /aɪ̯/
au → /aʊ̯/
eu, äu → /ɔʏ̯/
38./aɪ̯/: ei / ai
Examples:
mein /maɪ̯n/
Zeit /tsaɪ̯t/
Mai /maɪ̯/
Kaiser /ˈkaɪ̯zɐ/
Important:
ei ≠ /eɪ/
Standard German targets:
/aɪ̯/
39./aʊ̯/: au
Examples:
Haus /haʊ̯s/
auch /aʊ̯x/
bauen /ˈbaʊ̯ən/
Frau /fʁaʊ̯/
The vowel starts open and glides upward and back.
40./ɔʏ̯/: eu / äu
Examples:
heute /ˈhɔʏ̯tə/
neu /nɔʏ̯/
Häuser /ˈhɔʏ̯zɐ/
träumen /ˈtʁɔʏ̯mən/
eu and äu have the same standard pronunciation.
41.ei vs ie
One of the most important reading rules:
ei → /aɪ̯/
ie → /iː/
Compare:
mein /maɪ̯n/
Miene /ˈmiːnə/
Seite /ˈzaɪ̯tə/
sieben /ˈziːbən/
42.Vowel length can distinguish meaning
In many words, vowel length contributes to lexical contrast.
Examples:
Staat /ʃtaːt/
Stadt /ʃtat/
Beet /beːt/
Bett /bɛt/
Höhle /ˈhøːlə/
Hölle /ˈhœlə/
Length is therefore not merely stylistic.
43.Minimal pairs: i
Useful pairs:
| long | short |
|---|---|
| bieten /ˈbiːtən/ | bitten /ˈbɪtən/ |
| Miete /ˈmiːtə/ | Mitte /ˈmɪtə/ |
They illustrate both:
length
+
quality
44.Minimal pairs: e
Classic pair:
Beet /beːt/
Bett /bɛt/
The spelling signals the contrast through:
ee
vs
double consonant tt
45.Minimal pairs: a
A clear pair:
Staat /ʃtaːt/
Stadt /ʃtat/
The long and short vowels differ especially in duration.
46.Minimal pairs: ö
Compare:
Höhle /ˈhøːlə/
Hölle /ˈhœlə/
Both duration and openness change.
47.Minimal pairs: ü
Compare:
fühlen /ˈfyːlən/
füllen /ˈfʏlən/
This pair is especially useful because both vowels are unfamiliar to many learners.
48.Open and closed syllables
Simplified:
open syllable
→ ends in a vowel
closed syllable
→ ends in a consonant
Example:
le-ben
The first syllable is open.
Stressed open syllables often favour long vowels, but this is not an absolute rule.
49.Closed syllables and short vowels
Short vowels often occur before consonant clusters or doubled consonants.
Examples:
Bett
kommen
Mutter
sitzen
But:
Not every vowel before a consonant is short.
50.Double consonants as a short-vowel signal
Common pattern:
vowel + doubled consonant
→ vowel usually short
Examples:
Mitte
Bett
kommen
Mutter
Orthographically, the doubled consonant mainly signals the shortness of the preceding vowel.
51.ck and tz
Likewise:
ck
tz
typically follow a short vowel.
Examples:
backen /ˈbakən/
Jacke /ˈjakə/
sitzen /ˈzɪtsən/
Katze /ˈkatsə/
52.Lengthening h
An h after a vowel can signal length:
Zahn
Sohn
Uhr
sehen
Examples:
Zahn /tsaːn/
Sohn /zoːn/
This h is not pronounced as a separate consonant.
53.Doubled vowels
Doubled vowel letters often signal length:
aa
ee
oo
Examples:
Saal /zaːl/
See /zeː/
Boot /boːt/
Not all vowels use this spelling pattern.
54.ie as a strong length signal
ie very often represents:
/iː/
Examples:
Liebe
sieben
Tier
Brief
Important:
ie
is normally not a diphthong in German.
55.A single vowel letter can be long
Length does not always need an obvious spelling marker.
Examples:
Tag /taːk/
gut /ɡuːt/
Weg /veːk/
rot /ʁoːt/
So vowel length cannot be inferred only from h, doubled vowels, or ie.
56.A single vowel letter can be short
A single vowel letter can also represent a short vowel:
mit
weg
von
Bus
Spelling provides clues, but not a completely mechanical prediction.
57.ß and vowel length
ß follows a long vowel or diphthong.
Examples:
Straße /ˈʃtʁaːsə/
Fuß /fuːs/
heißen /ˈhaɪ̯sən/
Compare:
müssen /ˈmʏsən/
→ ss after a short vowel
58.ss and short vowels
ss typically follows a short vowel:
müssen /ˈmʏsən/
wissen /ˈvɪsən/
lassen /ˈlasən/
Contrast:
ß
→ after long vowel / diphthong
ss
→ after short vowel
59.Final devoicing does not change vowel length
Compare:
Tag /taːk/
Rad /ʁaːt/
Weg /veːk/
The final consonant is devoiced, but the vowel remains long.
Vowel length therefore needs to be learned independently of final devoicing.
60.Stress and vowel length
Full long/short vowel contrasts occur mainly in stressed syllables.
Unstressed syllables more often contain:
/ə/
/ɐ/
reduced vowels
Example:
leben /ˈleːbən/
Stressed:
/leː/
unstressed:
/bən/
61.Unstressed full vowels
Not every unstressed vowel becomes schwa.
Full vowels may remain, especially in loanwords, prefixes, and particular word structures.
Examples:
Musik
Hotel
Idee
Exact pronunciation depends on the word and its stress pattern.
62.Open vowels in loanwords
Loanwords may contain vowels and stress patterns that are less predictable from core German spelling conventions.
Examples:
Team
Chance
Service
Computer
Frequent loanwords are therefore best learned as complete sound forms.
63.Vowel before consonant clusters
Several following consonants often favour a short vowel:
Kind
Kunst
Helfer
Wörter
But historical and morphological exceptions exist.
So:
use the pattern
+
learn the lexical form
64.Morphology can reveal vowel length
Word families can help.
Examples:
fahren → Fahrt
nehmen → nahm
geben → gab
A form's pronunciation cannot always be predicted from its spelling alone; related forms may provide additional clues.
65.Umlaut and vowel length in word families
With umlaut, the length pattern is often preserved, though not mechanically in every word family.
Examples:
groß /ɡʁoːs/
größer /ˈɡʁøːsɐ/
Buch /buːx/
Bücher /ˈbyːçɐ/
Here the vowel remains long.
66.Short umlaut in word families
Examples:
Mann /man/
Männer /ˈmɛnɐ/
kurz /kʊʁts/
kürzer /ˈkʏʁtsɐ/
Shortness remains while vowel quality changes through umlaut.
67.Compounds and vowel length
In compounds, components normally retain their lexical vowel structure.
Example:
Haus + Tür
→ Haustür
The vowels follow the component words:
Haus /haʊ̯s/
Tür /tyːɐ̯/
68.Syllable boundary and vowel
Syllable boundaries can help explain spelling patterns.
Compare:
le-ben
Mit-te
Ofen
offen
Typical tendency:
stressed open syllable
→ more likely long
stressed closed syllable
→ more likely short
Do not treat this as an absolute rule.
69.Why spelling alone is not enough
German spelling provides many clues, but not every vowel length is explicitly marked.
For example:
Weg
weg
different lexical forms can show different vowel qualities.
Frequent words should therefore be learned together with their pronunciation.
70.Articulatory map: front and back
Vowels differ in where the tongue reaches its highest point.
Simplified:
front:
iː ɪ eː ɛ yː ʏ øː œ
central:
ə ɐ
aː a
back:
uː ʊ oː ɔ
These categories are especially useful for understanding ü and ö.
71.Articulatory map: close and open
The higher the tongue, the closer the vowel.
Simplified:
close:
iː yː uː
mid:
eː øː oː
more open:
ɪ ʏ ʊ ɛ œ ɔ
open:
a aː
These categories form a continuum; the table is a learning map.
72.Rounded and unrounded vowels
Especially rounded are:
/yː/ /ʏ/
/øː/ /œ/
/uː/ /ʊ/
/oː/ /ɔ/
Unrounded:
/iː/ /ɪ/
/eː/ /ɛ/
/aː/ /a/
Lip rounding is central to ü and ö.
73.Understanding ü from i
A useful articulatory relationship:
/iː/
→ keep the tongue position
→ round the lips
→ /yː/
Similarly:
/ɪ/
→ round the lips
→ /ʏ/
This is an articulation aid, not a spelling rule.
74.Understanding ö from e
Articulatory relationship:
/eː/
→ round the lips
→ /øː/
and approximately:
/ɛ/
→ round the lips
→ /œ/
This shows why ö is a front rounded vowel.
75.Do not replace length with loudness
A long vowel is not simply a louder vowel.
Wrong strategy:
long = louder
Correct:
long = longer duration
+
typical vowel quality
Stress and length are different properties.
76.Do not lengthen every stressed syllable
Not every stressed vowel is long.
Compare:
Miete /ˈmiːtə/
Mitte /ˈmɪtə/
Both first syllables are stressed.
Only Miete has a long vowel.
77.Do not over-open short vowels
Short vowels are often more open than their long counterparts, but not arbitrarily open.
For example:
/ɪ/
is not simply:
/ɛ/
and:
/ʊ/
is not:
/ɔ/
Each vowel quality remains distinct.
78.Common mistake: pronouncing every i as /i/
Problem:
bitten
with an overly close vowel.
Target:
bitten /ˈbɪtən/
not:
*/ˈbiːtən/
because that approaches bieten.
79.Common mistake: merging u and ü
Compare:
/uː/
→ back + rounded
/yː/
→ front + rounded
Examples:
gut /ɡuːt/
grün /ɡʁyːn/
Both are rounded; tongue position is the key contrast.
80.Common mistake: merging o and ö
Compare:
/oː/
→ back + rounded
/øː/
→ front + rounded
Examples:
Sohn /zoːn/
schön /ʃøːn/
The main difference lies in tongue position.
81.Common mistake: full e instead of schwa
An overly full final e can sound unnatural.
Example:
Bitte
Target:
/ˈbɪtə/
not a fully stressed:
*/ˈbɪteː/
82.Common mistake: pronouncing every r as a consonant
In words such as:
Mutter
Lehrer
besser
many standard varieties do not require a strong consonantal r.
Typical:
-er → /ɐ/
Regional standard pronunciations may differ.
83.Common mistake: reading ei as English-like
German:
ei → /aɪ̯/
Examples:
mein
Zeit
klein
This pattern is highly stable.
84.Common mistake: treating ie as two vowels
In most German words:
ie → /iː/
So:
Liebe
Tier
Brief
should not be pronounced as two separate vowels.
85.Common mistake: making au too narrow
The diphthong:
/aʊ̯/
begins clearly open.
Example:
Haus /haʊ̯s/
Starting too narrowly changes its natural quality.
86.Common mistake: pronouncing eu as two full syllables
eu normally represents a single diphthong:
/ɔʏ̯/
Example:
heute /ˈhɔʏ̯tə/
Not:
e-u
as two syllables.
87.Standard variation across the DACH region
Germany, Austria, and Switzerland have standard pronunciation varieties.
Variation may affect:
r realisation
quality of individual vowels
loanword pronunciation
prosody
The IPA forms shown here are a reference, not a claim that only one standard pronunciation exists.
88.Long ä in standard speech: practical rule
For learning, treat:
ä in words such as spät, Käse, wählen
→ as a long front e/ä-area vowel
Exact quality:
/ɛː/ ↔ closer to /eː/
may vary.
Correct length matters more than forcing an artificial distinction.
89.Quick decision: long or short vowel?
As a heuristic:
1. ie?
→ usually /iː/
2. doubled vowel or lengthening h?
→ usually long
3. doubled consonant, ck, tz?
→ usually short
4. ß?
→ preceding vowel long or diphthong
5. ss?
→ preceding vowel short
6. no clear marker?
→ check / learn the word's pronunciation
This is a reference heuristic, not an exceptionless rule.
90.Quick decision: which vowel quality?
For stressed core vowels:
long i → /iː/
short i → /ɪ/
long e → /eː/
short e/ä → /ɛ/
long o → /oː/
short o → /ɔ/
long u → /uː/
short u → /ʊ/
long ü → /yː/
short ü → /ʏ/
long ö → /øː/
short ö → /œ/
a differs more by duration than by quality.
91.Quick table: spellings
| Spelling pattern | typical pronunciation / function |
|---|---|
| ie | /iː/ |
| ei, ai | /aɪ̯/ |
| au | /aʊ̯/ |
| eu, äu | /ɔʏ̯/ |
| aa, ee, oo | long vowel |
| vowel + h | often long vowel |
| doubled consonant | preceding vowel usually short |
| ck, tz | preceding vowel usually short |
| ß | preceding vowel long / diphthong |
| ss | preceding vowel short |
92.Quick table: vowel pairs
| long | short | example contrast |
|---|---|---|
| /iː/ | /ɪ/ | bieten – bitten |
| /eː/ | /ɛ/ | Beet – Bett |
| /aː/ | /a/ | Staat – Stadt |
| /oː/ | /ɔ/ | Ofen – offen |
| /uː/ | /ʊ/ | gut – Mutter |
| /yː/ | /ʏ/ | fühlen – füllen |
| /øː/ | /œ/ | Höhle – Hölle |
93.Quick table: reduced vowels
| Sound | typical position | examples |
|---|---|---|
| /ə/ | unstressed -e, parts of endings | bitte, leben |
| /ɐ/ | often unstressed -er | Lehrer, Mutter |
These vowels are especially important in natural unstressed speech.
94.Quick table: diphthongs
| Sound | typical spellings | examples |
|---|---|---|
| /aɪ̯/ | ei, ai, ey, ay | mein, Mai |
| /aʊ̯/ | au | Haus, Frau |
| /ɔʏ̯/ | eu, äu | heute, Häuser |
Each diphthong forms one syllable nucleus.
95.What to check in a dictionary
For unfamiliar pronunciation, check:
IPA
primary stress
vowel length
loanword variant
plural or inflected forms
A dictionary entry can confirm spelling patterns or reveal exceptions.
96.What to store when learning a word
For a new word, store:
spelling
+
stress
+
vowel length
+
problematic sound
Example:
fühlen
→ first vowel long
→ /yː/
This makes pronunciation part of lexical knowledge.
97.Connection to the orthography reference
This page explains pronunciation.
For systematic spelling, the related reference topics are:
ss and ß
vowel length and spelling signals
The perspective differs:
here:
spelling → sound
orthography:
sound / structure → spelling
98.Connection to the r reference
Vocalised r appears here only insofar as it affects vowel structure:
-er → /ɐ/
vowel + r → often vocalised
The full range of German r variants belongs in the dedicated r reference.
99.Connection to word stress
Vowel length and word stress interact, but are not identical.
Important:
stressed
≠ automatically long
unstressed
→ often more reduction
The full stress system belongs in the separate word-stress reference.
100.Minimum reference for beginners
For A1–A2, prioritise:
ei ≠ ie
au
eu / äu
long vs short vowels
ü and ö
schwa in -e
-er → often /ɐ/
These patterns cover a large amount of high-frequency vocabulary.
101.Minimum reference for B1–B2
At B1–B2, also control:
quality contrasts /iː–ɪ/, /uː–ʊ/, /oː–ɔ/
long and short umlaut vowels
reduction of unstressed endings
orthographic length signals
loanwords as distinct sound forms
102.Minimum reference for C1
At C1, vowel production should be:
stable
intelligible
reliable across registers
controlled even at higher speech rates
Fine-grained goals include:
natural reduction
secure technical vocabulary
recognising regional variation
maintaining length in complex words
103.Checklist for an unfamiliar word
For a new word:
1. Where is the stress?
2. Which vowel is stressed?
3. Is there ie, a doubled vowel, or h?
4. Is there a doubled consonant, ck, tz, or ss?
5. Is there ß?
6. Is there a diphthong?
7. Is there unstressed -e or -er?
8. Is it a loanword?
Then infer the pronunciation.
104.Core distinction: letter vs sound
A letter is not the same thing as a sound.
For example:
e
can represent:
/eː/
/ɛ/
/ə/
depending on the word.
This reference therefore combines:
spelling
+
IPA
+
example word
105.Core distinction: length vs quality
For most German vowel pairs, both of these matter:
duration
+
vowel quality
Especially:
/iː/ – /ɪ/
/eː/ – /ɛ/
/oː/ – /ɔ/
/uː/ – /ʊ/
/yː/ – /ʏ/
/øː/ – /œ/
With a, duration plays a larger role.
106.The core idea
The German vowel system becomes clearer when seen not as isolated letters, but as interacting dimensions:
long ↔ short
close ↔ open
front ↔ back
unrounded ↔ rounded
full ↔ reduced
monophthong ↔ diphthong
Spelling gives strong clues, but the final unit to learn is the spoken word.
107.Summary
Key reference points:
1. Length and quality interact.
2. /iː–ɪ/, /eː–ɛ/, /oː–ɔ/, /uː–ʊ/, /yː–ʏ/, /øː–œ/ are core contrasts.
3. /aː–a/ differs especially in duration.
4. Schwa /ə/ and /ɐ/ shape unstressed syllables.
5. /aɪ̯/, /aʊ̯/, /ɔʏ̯/ are the core diphthongs.
6. ie, h, and doubled vowels often signal length.
7. Doubled consonants, ck, tz, and ss often signal shortness.
8. ß follows a long vowel or diphthong.
9. Spelling helps but does not replace lexical pronunciation knowledge.
10. Intelligibility matters more than artificially eliminating standard regional variation.
