noun 下载 🔗分享 摩擦音 Any of several sounds produced by air flowing through a constriction in the oral cavity and typically producing a sibilant, hissing, or buzzing quality; a fricative consonant. Examples : "The teacher explained that the sounds /f/, /v/, /s/, and /z/ are all fricatives because they are made by forcing air through a narrow channel in the mouth, creating a hissing sound. " 老师解释说，/f/、/v/、/s/ 和 /z/ 这些音都是摩擦音，因为发音时需要让气流通过口腔中的狭窄通道，从而产生一种嘶嘶的声音。 phonetics language linguistics sound 与AI对话词汇游戏阅读练习
