During his tenure, Doke developed and promoted a method of linguistic analysis and description of the Bantu languages that was based upon the structure of these languages. The "Dokean model" continues to be one of the dominant models of linguistic description in Southern and Central Africa. His classification of the Bantu languages was for many years the dominant view of the interrelations among the African languages. He was also an early describer of Khoisan and Bantu click consonants, devising phonetic symbols for a number of them.
