Page "Clement Martyn Doke" Paragraph 9

At the request of the government of Southern Rhodesia, Doke investigated the range of dialect diversity among the languages of the country and made recommendations for Unified Shona.

This formed the basis for Standard Shona.

He devised a unified orthography based on the Zezuru, Karanga and Manyika dialects.

However, Doke's orthography was never fully accepted and the South African government introduced an alternative, leaving Shona with two competing orthographies between 1935 and 1955.
