Xamtanga language

Xamtanga (also Agawinya, Khamtanga, Simt'anga, Xamir, Xamta) is a Central Cushitic language spoken in Ethiopia by the Xamir people.

Vowels
The central vowels have fronted and backed allophones, depending on the adjacent consonant(s).

Consonants

 * is found only word-initial in loanwords, and may be glottal or pharyngeal.
 * is alveolar before the vowel, dental otherwise.
 * can be ejective, and in some cases the ejectives appear to be in free variation with the voiceless plosives.

Gemination
In positions other than word-initial, Xamtanga contrasts geminate and non-geminate consonants. With most consonants, the difference between a geminate and a non-geminate is simply one of length, but the cases of are more complex. When not word-initial, non-geminate is realized as a bilabial  or labiodental fricative, and  and  are realized as affricates:. Their geminate equivalents may be realized as prolonged, or can simply be short.

In word-initial position, geminate consonants do not occur, and /b t q/ are realized as plosives.
