Arguments

According to Roger Blench, there are five different tones in Kuteb, these are: low (unmarked), mid (¯), high (´), falling (ˆ), and rising (ˇ). The fifth tone, (rising) is only created through sandhi changes that affect some vocabulary after an "upstep".^[3] According to W.E. Welmers, this sandhi change does not occur, and if it did, only the pronunciation would change, not the written diacritic as well.^[6]

Syllabic boundaries

In Kutep, like in other Jukunoid languages, most consonantal phonemes can either be labialized or palatal. If these changes are taken to be consonantal phonemic clusters, the syllabic boundaries are as follows:^[7]

Sandhi changes

The letter ⟨w⟩ in the Kuteb language retains its status as a voiced labio-velar approximant, as in uwé ‘face’ or in wōm ‘dry’ - though, when ⟨w⟩ is included in clusters with a palatal consonant (/c, j, sh, nj/) /w/, due to sandhi changes, becomes a voiced or voiceless labiodental release.

Distribution of consonants

In Kuteb, there are many consonant clusters that can exist, though, most of these occur between word boundaries, though, some of these do occur in single-syllable isolation - these syllables are listed below. Theoretically though, any combination of syllable-final consonants (see below) followed by any syllable-initial consonant is possible. It is likely, however, that reduction would occur, as in the word ushitong ‘soup-stirrer’ (from shir and utoŋ) in which the /r/ has been dropped. Also, when final ⟨nn⟩ ^{[note 1]} stems precede stems beginning with ⟨n⟩, the double ⟨nn⟩+⟨n⟩ is reduced to just ⟨n⟩. This effect can be shown in words such as munae (munn-náe) ‘be abundant’, and in munji (munn-nji) ‘forget’.^[8]

In CV positions, the following consonants are used:^[8]

• p ts t c k b (d) (g) mb nd nj ŋg f s sh h v z nz m n ŋ r l

While in C(C)VC final positions, the following are used instead:

• b r g m n* ŋ*

And the following are used in CC clusters:

• With Cw: pw, mbw, bw, fw, mw, sw (?), cw, njw, jw, shw, kw, ngw, and ŋw ^{[note 2]}
• With Cy: py, mby
• With Ck: pk, tk, fk, sk
• With Cg: mbg, ndg

Consonant clusters

In 1964, Peter Ladefoged recorded the phonetics of multiple West African languages. One of these languages was Kuteb, and these were his findings:^[9]
