Tabaru language
Tabaru is a North Halmahera language of Indonesia.
Phonology
Vowels
Tabaru has a simple five vowel system: a, e, i, o, u.
On the surface level, Tabaru only allows syllables of the type V. Words with an underlying final consonant add an echo vowel: ′child′, ′drink′, ′paddle′, ′eat′, ′answer′. The echo vowel is dropped when a suffix is added: ′hear′, but ′heard′. Stress regularly falls on the penultimate syllable, but shifts to the antepenultimate when the word takes an echo vowel.
