 * /w, j/ are the only initial consonants permitted to form consonant clusters with other consonants. Old Dieuese also had medial /ɹ, l/, but they have disappeared.
 * /p, b, ɓ, m/ are bilabial while /f, v/ are labiodental.
 * /t, tʰ, d, ɗ/ are denti-alveolar, /s, z, ʂ, ʐ/ are laminal, and /n, ɻ, l/ are apical.
 * A glottal stop [ʔ] is inserted before words that begin with a vowel or semivowel.
 * /ɸ, β/ are allophones of /f, v/ before rounded vowels.
 * Implosives /ɓ, ɗ, ᶑ, ʄ/ are in free variation with voiced plosives /b, d, ɖ, ɟ/.

 * All vowels are unrounded except for the three back rounded vowels: /u, o, uə/.
 * The unrounded back vowels /ɯ, ɤ, ɯə/ are near-back [ɯ̟, ɤ̟, ɯ̟ə] and become [ɨ, ə, ɨə] after palatalized consonants.
 * /e, ɤ, o/ are mid /e̞, ɤ̞, o̞/.
 * /a/ is central /ä/.

Tones
Like many East Asian languages, Dieu uses tone to distinguish words, with the number of possible tones depending on the type of final. In finals that end in a stop, the number of tones is reduced to three. Tones only occur in Chinese loanwords.

There are 7 phonetic tones in Dieu: high, mid, low, high rising, low rising, high falling, low falling.
