Jyutping is a romanisation system for Cantonese developed by the Linguistic Society of Hong Kong (LSHK), an academic group, in 1993. Its formal name is the Linguistic Society of Hong Kong Cantonese Romanization Scheme. The LSHK advocates for and promotes the use of this romanisation system.
The name Jyutping (itself the Jyutping romanisation of its Chinese name, 粵拼) is a contraction consisting of the first Chinese characters of the terms Jyut6jyu5 (粵語, meaning "Yue language") and ping3jam1 (拼音 "phonetic alphabet", also pronounced as "pinyin" in Mandarin).
The Yale romanization of Cantonese was developed by Gerard P. Kok for his and Parker Po-fei Huang's textbook Speak Cantonese initially circulated in looseleaf form in 1952 but later published in 1958. Unlike the Yale romanization of Mandarin, it is still widely used in books and dictionaries, especially for foreign learners of Cantonese. It shares some similarities with Hanyu Pinyin in that unvoiced, unaspirated consonants are represented by letters traditionally used in English and most other European languages to represent voiced sounds. For example, [p] is represented as b in Yale, whereas its aspirated counterpart, [pʰ] is represented as p. Students attending The Chinese University of Hong Kong's New-Asia Yale-in-China Chinese Language Center are taught using Yale romanization.
