bag)This datasheet is for cv-corpus-26.0-2026-06-12 of the Mozilla Common Voice Scripted Speech dataset for Tuki [Tukí - bag]. The dataset contains 7106 clips representing 11.12 hours of recorded speech (11 hours validated) from 14 speakers, recorded from a text corpus of 1,012 sentences.
Tuki is an indigenous language of Cameroon. It belongs to the Niger-Congo language family. According to Ethnologue, the vitality status of the Tuki is stable, and the language is used as a first language by everyone in the ethnic community. However, this is not confirmed by any recent study. In fact, given the general negative trend in the vitality of indigenous languages in Cameroon and other parts of Africa due to factors such as rural exodus, the shift to colonial languages such as French, and language policy, among others, it is more likely that the vitality of Tuki is threatened.
The Administrative Atlas of Cameroon's Languages (Breton and Bikia Fohtung 1993) lists 6 dialects of Tuki:
Tungoro spoken by the Aki around the Ngoro Subdivision
Tukombe spoken by the Kombe (or Bakombe)
Tonjo spoken by the Nju (or Bunju)
Tutsingo spoken by the Tsingo (or Batsingo)
Tocenka spoken by the Tiki also known as Bacenga
Tumbele spoken by the Mbele (also known as Bambele)
Of the 6 dialects, two are reprensented in the dataset, namely, Tukombe and Tutsingo.
