Phonology

Vowels

• /i/ varies between close front unrounded [i], near-close front unrounded [i̞] and close-mid front unrounded [e].^[2]
• /u/ varies between near-close near-front rounded [ʊ] and close-mid back weakly rounded [o̜], with the latter realization being the most usual.^[2]
• /ɘ/ varies between mid near-front unrounded [ɛ̽] and close-mid central unrounded [ɘ].^[2]
  • /ɘ/ is shorter than the other vowels, particularly between voiceless consonants.^[2]
  • The sequence /ɘn/ is sometimes realized as a syllabic [n̩].^[2]
• /a/ varies between open central unrounded [ä] and near-open retracted front [æ̠].^[2] 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].^[2]

Consonants

• /m, p/ are bilabial, whereas /w/ is labialized velar.
• /tʃ/ is an affricate, rather than a plosive.^[3] 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].^[4]
  • In the syllable coda, /n/ is realized with a wider contact, maximally dentoalveolo-velar [n̪͡ŋ].^[4]
  • After /u, a/, the denti-alveolar contact is often not made, which makes /n/ sound more like a velar nasal [ŋ].^[4]
  • /ð/ may sometimes sound as if it were a lateral consonant, but it is never realized as lateral.^[2]
• /ɲ, ʎ/ are dentoalveolo-palatal [ɲ̪, ʎ̪].^[4]
  • /ʎ/ is sometimes realized as a weak fricative [ʎ̪˔].^[2]
• /h/ occurs only in the affirmative interjection [ahã].^[3]
• /r/ is realized as a flap [ɾ] in the syllable onset and as a trill [r] in the syllable coda.^[4]
• /ˀr/ is a glottalized flap [ˀɾ]. Intervocalically, it is realized as a sequence [ɾʔ].^[4]
