Sibilant

咝音

A term in the phonetic classification of sounds on the basis of manner of articulation. It refers to a fricative sound made by producing a narrow, groove-like stricture between the blade of the tongue and the back part of the alveolar ridge. These sounds, such as [s] and [ʃ], have a high-frequency hiss characteristic. Sounds which lack this feature could be called non-sibilant.

语音学按发音方式给语音分类，指舌叶和齿龈隆骨后部之间狭窄、有如舌沟的制流发出的擦音。这类音，如[s]和[ʃ]，有频率很高的咝咝声特征。缺乏这一特征的音称作非咝音。
