[1] The consonant inventory comprises 18 phonemes (ᵐb, t, ⁿd, k, ᵑɡ, kʷ, ᵑɡʷ, m, n, ŋ, ɸ, ʦ, ⁿʣ, ð, s, r, w, j).

The system consists of a series of obstruents (oral and prenasalized plosives and affricates), fricatives, nasals and semivowels.

Many syllables and many words in Komnzo lack a specified vowel, e.g. mnz 'house' [mə̆nts] or gwth 'nest' [ᵑɡʷə̆θ].

The current orthography of Komnzo does not represent the epenthetic vowel because it can be predicted by the rules of syllabification.

Komnzo number words use a senary numeral system, with the following powers: nibo (61), fta (62), taruba (63), damno (64), wärämäkä (65) and wi (66).
