That is, it is the "z" sound in English pronounced with rounded lips, and treated as a vowel in a syllable. It is used by Sinologists when transcribing words from various languages. The standard IPA notation would be [z̩ʷ][citation needed]. See Obsolete and nonstandard symbols in the International Phonetic Alphabet for more information.[1]
