## Phonology

### Vowels

Monophthong phonemes :

| | Front | Central | Back |
| - | - | - | - |
| Close | i | | u |
| Mid | | ɘ | |
| Open | | a | |

* /i/ varies between close front unrounded [i], near-close front unrounded [i̞] and close-mid front unrounded [e].
* /u/ varies between near-close near-front rounded [ʊ] and close-mid back weakly rounded [o̜], with the latter realization being the most usual.
* /ɘ/ varies between mid near-front unrounded [ɛ̽] and close-mid central unrounded [ɘ].
   * /ɘ/ is shorter than the other vowels, particularly between voiceless consonants.
   * The sequence /ɘn/ is sometimes realized as a syllabic [n̩].
* /a/ varies between open central unrounded [ä] and near-open retracted front [æ̠]. The vowel chart in Valenzuela & Gussenhoven (2013) puts /a/ in the near-open central position [ɐ].
   * In closed syllables, /a/ is realized as open-mid central unrounded [ɜ].

### Consonants

Consonant phonemes :

| | | Labial | Alveolar | Palatal | Velar | Glottal |
| - | - | - | - | - | - | - |
| Nasal | Nasal | m | n | ɲ | | |
| Stop | Stop | p | t | tʃ | k | ʔ |
| Fricative | Fricative | | s | ʃ | | (h) |
| Trill | plain | | r | | | |
| Trill | glottalized | | ˀr | | | |
| Approximant | central | w | ð | j | | |
| Approximant | lateral | | l | ʎ | | |

* /m, p/ are bilabial, whereas /w/ is labialized velar.
* /tʃ/ is an affricate, rather than a plosive. It has nevertheless been placed in the table in that manner to save space.
* /n, t, ð, l/ are laminal denti-alveolar [n̪, t̪, ð̪, l̪].
   * In the syllable coda, /n/ is realized with a wider contact, maximally dentoalveolo-velar [n̪͡ŋ].
   * After /u, a/, the denti-alveolar contact is often not made, which makes /n/ sound more like a velar nasal [ŋ].
   * /ð/ may sometimes sound as if it were a lateral consonant, but it is never realized as lateral.
* /ɲ, ʎ/ are dentoalveolo-palatal [ɲ̪, ʎ̪].
   * /ʎ/ is sometimes realized as a weak fricative [ʎ̪˔].
* /h/ occurs only in the affirmative interjection [ahã].
* /r/ is realized as a flap [ɾ] in the syllable onset and as a trill [r] in the syllable coda.
* /ˀr/ is a glottalized flap [ˀɾ]. Intervocalically, it is realized as a sequence [ɾʔ].
