Vaeakau-Taumako phonology

Vowels
Vaeakau-Taumako does not vary from the standard Polynesian and Austronesian vowel system, featuring five vowels that can be used either in a long or short form. Short vowels found in word-final syllables are frequently devoiced or dropped, but long vowels in the same position are always stressed. There is little allophonic variation between vowel pronunciations.

Vowel sequences in Vaeakau-Taumako are typically not treated as diphthongs, as they are not fully reduplicated, as shown in the word "holauhola". This is despite the vowels in the original word being pronounced like a diphthong.

Consonants
The Vaeakau-Taumako language has one of the most complex consonant system of the Polynesian languages, with 19 distinct phonemes, plus a large amount of variation across dialects. /b/ and /d/ are found primarily in loan words, rather being native to the language.

Aspirated sounds are characteristic of the language, and are typically strong and audible. However, the use of aspirated sounds varies across dialects, enough that it is difficult to identify a consistent pattern aside from noting they always occur at the start of stressed syllables.
