Williamson of the University of Port Harcourt and the Rivers Readers Project, to work with the then Obolo language committee. Faraclas analyzed the language and wrote an extensive description of the phonology and grammar to the language, and helped to design the Orthography.
The Obolo consonants segment range between twenty one and twenty seven. Phonetically, Obolo has twenty seven phonetics consonant sounds according to the following groupings: ten stops, four nasals, eight fricatives, one trill, 1 tap and three approximants.
There are no nasalized vowel phonemes in Obolo, but all vowels may become slightly nasalized in the environment of a nasal consonant, According to Faraclas Obolo does not permit consonant clustering in a word. Instead of clustering to occur, and epenthesis vowel is usually inserted to break the clustering.
