Shüpamom — Bamun (bax)

This datasheet is for cv-corpus-26.0-2026-06-12 of the Mozilla Common Voice Scripted Speech dataset for Bamun [Shüpamom - bax]. The dataset contains 8668 clips representing 11.83 hours of recorded speech (10.62 hours validated) from 13 speakers, recorded from a text corpus of 1,030 sentences.

Language

Bamun or Shüpamom/Shupamem is a Bantu-Grassfield language spoken in the Noun Divison, West Region in Cameroon.

Variants

The Bamun language is quite homogeneous within their indigenous territory, the Noun Administrative Division. However, the Administrative Atlas of Cameroon's Languages (Breton and Bikia Fohtung, 1991) indicates a few "islands" outside the Noun Department where the Bamun language exhibits minor variations. These include Bapi in the Mifi Division in the West Region and Bamalang and Bangolan in the Mezam Division in the Northwest Region.

The variant represented in the collection of sentence prompts is that spoken in the Noun Division.
