Wong Shik-Ling (also known as S. L. Wong) published a romanisation scheme accompanying a set of phonetic symbols for Cantonese based on International Phonetic Alphabet (IPA) in the book A Chinese Syllabary Pronounced according to the Dialect of Canton.
Cantonese, like a number of other varieties of Chinese is monosyllabic. Each syllable is divided into initial (consonant), final (vowel and following consonant) and tone.
Chinese phonology traditionally stresses on finals because it is related to rhymes in the composition of poems, proses and articles. There are 53 finals in Cantonese.
The ten basic vowel phoneme symbols [a], [ɐ], [ei], [ɛ], [i], [ou], [ɔ], [œ], [u] and [y] in the scheme mean following:
For detail explanation of the phonetic system, see S. L. Wong (phonetic symbols)#Vowels.
All vowel phonemes except a formed vowel 9 finals themselves.
Some vowel phonemes can followed by vowel phonemes -i, -u or -ue to form 8 falling diphthong finals:
For detail explanation of the phonetic system, see S. L. Wong (phonetic symbols)#Falling diphthong finals.
The nasal consonants [m], [n] and [ŋ] in finals can be written as:
Some vowel phonemes can followed by nasal consonants -m, -n or -ng to form 17 nasal phoneme finals:
For detail explanation of the phonetic system, see S. L. Wong (phonetic symbols)#Nasal phoneme finals.
The plosive final can be written [p], [t] and [k] as:
Some vowel phonemes can followed by inaspirated plosive consonants -p, -t or -k to form 17 plosive phoneme finals:
