The inventory of vocalic phonemes is larger than average, with ten present:

            Front                   Back
            Unrounded   Rounded     Unrounded   Rounded
High        i           y           ɯ           u
Mid         e           ø           ɤ           o
Low                                 a           ɶ

Despite their position in the phoneme table above, /a/ and /ɶ/ are not treated as back vowels but as central ones; in formal speech, they are typically pronounced centralized, as [ä] and [ɶ̈]. This ideally would result in a symmetric vowel system.

The actual realization of the vowel phonemes can show considerable variation by dialect, but as a rule, the rounding distinctions are preserved. In many dialects the rounded front vowels and the unrounded back vowels are centralized to some extent, especially in unstressed positions. This tends to cause both /y/ and /ø/ to approach [ʏ], while /ɯ/ becomes [ɯ̽] and /ɤ/ becomes [ʌ̽]. Many of these dialects also realize /ɶ/ as [ɔ̽], with such vocalization again more common in unstressed positions. 

Centralization of /i/, /e/, /u/, /o/, or /a/ is less common; these phonemes are realized more consistently across dialect, whether stressed or unstressed, as [i], [e̞], [u], [o̞], and [ä], respectively, though they may lose some vowel quality when unstressed.

In addition to the above variations in realization, unstressed vowels are in all dialects shorter than stressed vowels.

Diphthongs exist in /w/ and /j/, but /w/ can only occur before unrounded vowels. All vocalic variations still apply to the vocalic elements of diphthongs.

Nine basic vowel qualities: / a æ e ə i o œ u ʌ / Basic vowels undergo diphthongization (fronting, backing, closing, centring) and variations in phonation (length, tenseness, rhoticity, breathiness, creakiness)

Full vowel phoneme inventory (38 total) (followed by standard romanization):

a (6): /a a̰ː a̰ɪ̯ a̰ʊ̯ a̰˞ː a̤/ (a, aa, ai, ao, ar, ah)

æ (1): /æi̯/ (aiy)

e (4): /ɛ ej ɛə̯ ɛ̤ç/ (e, ey, ea, eh)

ə (3): /əi̯ ɚː ɚ̰ː/ (ay, ur, er)

i (7): /ɪ iː iə̯ iɔ̯ iə̯ʊ̯ ɪ̤ç i̤ə̯/ (i, ee, ia, io, iau, ih, iah)

o (6): /ɔ ɔ̰ ɔ̯o ɔ̰ɪ̯ ɔ̰˞ː ɔ̤/ (o, au, oa, oy, or, oh)

œ (3): /œ øœ̯ œɔ̯/ (eu, euu, euo)

u (6): /ʊ uː ʊɪ̯ uə̯ uə̯ɪ̯ ʊ̤/ (ou, oo, ui, ua, ooay, ooh)

ʌ (2): /ʌ ʌu̯/ (u, uoo)

Notes:

  • both rhoticity and creaky voice appear only in /a/, /ə/ and /o/
  • rhoticity does not occur without vowel lengthening
  • Three of the four rhotic vowels also occur with creaky voice /ɚ̰ː/, /a̰˞ː/ and /ɔ̰˞ː/. Only /ɚː/ occurs without creaky voice.
  • except in /a/, non-diphthongal, non-rhotic lengthening is always concurrent with a change in tenseness
  • breathy voice does not occur with any other phonation type, and aside from the diphthong /i̤ə̯/, appears only in clear short vowels
  • /ə/ and /æ/ do not appear as clear short vowels

There are 8 vowels:

<A,a> ==== /e̞/

<Ȧ,ȧ> ==== /ä/

<E,e> ==== /ɪ/

<Ee,ee> === /ɶ/

<I,i> ==== /ɛ/

<Ii,ii> === /i/

<O,o> ==== /ɞ/

<u> ==== /ɶ/

<u> never occurs at the beginning of a word, therefore no majuscule is necessary.
