Avatime, also known as Afatime, Sideme, or Sia, is a Kwa language of the Avatime (self designation: Kedone (m.sg.)) people of eastern Ghana. The Avatime live primarily in the seven towns and villages of Amedzofe, Vane, Gbadzeme, Dzokpe, Biakpe, Dzogbefeme, and Fume.

Phonology

Avatime is a tonal language with three tones, has vowel harmony, and has been claimed to have doubly articulated fricatives.

Vowels

Avatime has nine vowels, /i ɪ e ɛ a ɔ o ʊ u/, though the vowels /ɪ ʊ/ have been overlooked in most descriptions of the language. It is not clear if the difference between /i e o u/ and /ɪ ɛ ɔ ʊ/ is one of advanced and retracted tongue root (laryngeal contraction), as in so many languages of Ghana, or of vowel height: different phonetic parameters support different analyses.Since the IPA does not have distinct letters for ±ATR vowels, they are transcribed here as differing in height for legibility.

Avatime has vowel harmony

Vowel harmony

Vowel harmony is a type of long-distance assimilatory phonological process involving vowels that occurs in some languages. In languages with vowel harmony, there are constraints on which vowels may be found near each other....

. A root many not mix vowels of the relaxed /i e o u/ and contracted /ɪ ɛ a ɔ ʊ/ sets, and prefixes change vowels to harmonize with the vowels of the root. For example, the human singular gender prefix is /ɔ ~ o/, and the human plural is /a ~ e/: /o-ze/ "thief", /ɔ-ka/ "father"; /be-ze/ "thieves", /ba-ka/ "fathers"; also /o-bu/ "bee" but /ɔ-bʊ/ "god".Tone not marked. Other prefixes vary as /ɛ ~ e/

Vowels may be long or short. Records from 1910 showed that all vowels could be nasalized, but that is disappearing, and few words with nasal vowels remained by the end of the century.

The language has been claimed to have doubly articulated

Doubly articulated consonants are consonants with two simultaneous primary places of articulation of the same manner . They are a subset of co-articulated consonants. They are to be distinguished from co-articulated consonants with secondary articulation, that is, a second articulation not of the...

 fricatives /x͡ɸ ɣ͡β/. However, as with similar claims for Swedish [ɧ], the labial articulation is not fricated, and these are actually labialized velars, /xʷ ɣʷ/. All velar fricatives are quite weak, and are closer to [h ɦ hʷ ɦʷ].

The affricates vary between [t͡s], [d͡z] and [t͡ʃ], [d͡ʒ], which may be a generational difference.

Phonotactics

Syllables are V, CV, CGV, and N: Avatime allows consonant-approximant clusters, where the approximant may be /l/, /w/, /j/. There is also a syllabic nasal, which takes its own tone: /kpāŋ̄/ "many".

Any consonant but /n/, /l/ may form a cluster with /l/: /ɔ̀kplɔ̄nɔ̀/ "table", /ɔ̀ɡblāɡɛ̄/ "snake", /káɣʷlɪ̀tsã̀/ "chameleon", /sɪ̄ŋʷlɛ̀sɛ̃̀/ "mucous". After a coronal consonant

When two vowels come together, they are either separated by a glottal stop [ʔ], fuse into a single vowel, or the first vowel reduces to a semivowel

s reduce to [j] and three of the back vowels reduce to [w], but /u/ is fronted to [ɥ].
