The O’otham alphabet is a streamlined 24-letter writing system built from the Latin script. It includes 5 vowels (A, E, I, O, U) and 19 consonants, along with two distinctive digraphs—letter pairs that blend to create single, unique sounds. Like many modern alphabets, it uses both uppercase and lowercase forms.

This tab explores the vibrant sound system of Akimel O’otham vowels—the living breath of the language. Vowels are created when air flows freely through the vocal tract, shaped but never blocked, and are represented by the letters A, E, I, O, and U.

They range from crisp, short sounds—like the “a” in ash or laugh—to extended, resonant long vowels—such as the “a” in a:li or baby. These sounds form the heart of every syllable, giving words their rhythm and voice.

Among them are monophthongs, steady single vowel tones, and diphthongs, dynamic blends where two vowel sounds glide together within the same syllable. Together, they create the rich vocal texture that defines Akimel O’otham speech.

Diphthong (combination sounds/Go:k Eve:m Kaithag) vowels within Akimel O'otham orthography. A diphthong is a living, moving vowel — a vocalic “glide” where one sound flows into another within a single syllable. Instead of holding the mouth in one steady position, the voice travels, shaping meaning through motion. The term comes from Greek di (two) and phthongos (sound), literally “two sounds in one.” O'otham orthography includes eight recognized diphthongs, /ai/ (eye), /ei/ (O'otham unique sound), /ia/ (yeah), /io/ (ee yaw), /iu/ (ee you), /oi/ (boy), /ua/ (wa), and /ui/ (we).
