=== Vowels ===
Vowels qualities are {{IPA|/a e i ɨ u o/}}. Vowels may be nasalized and/or show creaky voice, under which tones are lowered.<ref name=":0">Anderson, Doris, ''Conversational Ticuna'', Summer Institute of Linguistics, 1962</ref> There are diphthongs {{IPA|/ai̯/}} and {{IPA|/au̯/}} that carry a single tone, contrasting with vowel sequences {{IPA|/ai/}} and {{IPA|/au/}} that carry two tones.

The six vowels may be nasal or laryngealized. The sixth vowel is spelled ''ü''.
