Barnett-chao

The Barnett-Chao (abbreviated here as B-C) system of romanization for writing Cantonese is based on the principles of the Gwoyeu Romatzyh system (abbreviated as GR) for writing Mandarin Chinese in the Latin alphabet. The Barnett-Chao system has had a limited following and appears almost exclusively in Y.R. Chao's "Cantonese Primer". The two reasons for its lack of widespread adoption despite the inherent benefits of tonal spelling are that it 1) requires a large number of roman letters to represent each toned syllable, and 2) is even more complex than the already challenging GR system, as it also encodes the high and low registers of Cantonese as well as the variant tones (變調) of spoken Cantonese.

Description

Like GR spelling, B-C spelling uses contrasting unvoiced/voiced pairs of consonants to represent aspirated and unaspirated sounds. B-C also uses single versus double vowels letters to represent certain short + high versus long + low final vowels even in open syllables where the contrast does not exist: "buk", "buut", "baa", and different letters to represent the contrast in other cases: "sek", "sin". Some vowels are only long and do not use doubling to represent length: "ea, o, y".

The Cantonese high and low pitch registers are indicated by inserting "-h-" or "-r-" between the initial and final: "bhat", "brat". Medium pitch register has no insert, and is considered the basic form: "baa".
