Previous research includes a study of noun classes in Beboid languages by Jean-Marie Hombert (1980), Larry Hyman (1980, 1981), a dissertation by Richards (1991) concerning the phonology of three eastern Beboid languages (Noni, Ncane and Nsari), Lux (2003) a Noni lexicon and Cox (2005) a phonology of Kemezung.

The Largest Language is the Fang Language of Cameroon SIL International survey reports have provided more detail on Eastern and Western Beboid (Brye & Brye 2002, 2004; Hamm et al. 2002) and Hamm (2002) is a brief overview of the group as a whole.

Eastern Beboid is clearly valid; speakers recognise the relationship between their languages, their distribution is the result of recent population movements and linguistically they are similar, and they are close to the Bantu languages.

Western Beboid, on the other hand, is a geographic rather than genetic group: some appear to be closer to the Grassfields languages, and there does not appear to be much to link them together, though this may be partly due to lack of data (Good 2009, Di Carlo & Good 2012).

Below is a list of language names, populations, and locations (in Nigeria only) from Blench (2019).
