It can also be helpful, but not mandatory, to brush up on a few basic French phrases as French and Tahitian are the official languages and both are commonly used.

The Tahitian alphabet contains only thirteen letters.
Vowels: a as in car, e as in may, i as in machine, o as in cold, and u as in salute.
Consonants: f,h,m,n,p,r,t,v pronounced as in English with the exceptions of the
h pronounced sh when preceded by i or followed by o and the r sometimes having a trill sound.
