The Chinese Journal of Phonetics, organized by the Department of Phonetics, Institute of Linguistics, Chinese Academy of Social Sciences, and published twice a year, is an important publication platform for the Chinese phonetics community, and it presents new achievements in phonetics. Phonetics is a sub-discipline of linguistics that studies the sounds of speech (i.e., speech sounds). Phonetics, in the narrow sense, corresponds to the English term phonetics, which focuses on the nature of specific sounds and the methods of producing them, as opposed to phonology, which studies the abstract rules and systems of phonology that govern the operation of phonemic or phonological distinctive features in a given language. As this year marks the centenary of the birth of Mr. Wu Zongji, the results of Mr. Wu's phonetics are especially highlighted in this issue, in order to deeply commemorate the memory of Mr. Wu and other phonologists of the older generation. This issue contains a large number of experimental phonological results, including phonological analyses of Wu, Cantonese and other Chinese dialects. Phonetics is playing an increasingly important role in the field of network technology.
