Abstract
Kibushi is a principally oral language, which is spoken in Mayotte, a multilingual French island located between Madagascar and the Comoros Archipelago in the Mozambique Channel. The aim of this article is to study the two dialects of Kibushi: Kisakalava, used in a dozen villages with some twenty thousand speakers, and Kiantalautsi, spoken mostly in two villages, Ouangani and Poroani, by a few thousand speakers. 19 speakers in Kisakalava and 9 in Kiantalautsi were recorded producing 19 words. Results show a vowel space slightly different between the two dialects, as well as variation between villages.
