Sharp

舌高[音]

One of the features of sound set up by Jakobson and Halle in their distinctive feature theory of phonology, to help handle secondary articulations - in this case, palatalization. ‘Sharp’ consonants are defined both articulatorily and acoustically as sounds produced with the tongue being raised towards the hard palate during their articulation, and with a relatively wide area behind the stricture; there is a consequent greater intensity of some of the higher frequencies of the sound spectrum. All palatalized consonants are [+sharp]. The feature is not used in the Chomsky and Halle system.

雅克布逊和哈勒在其音系学的区别特征理论中确立的语音特征之一，用来描写次发音动作——这里指腭化。“舌高”辅音从发音和声学两方面定义为：发音时舌朝腭方向抬高，制流后有一较宽的区域，结果造成频谱上某些高频的强度增大。所有的腭化辅音都有[+舌高]特征。这个特征在乔姆斯基和哈勒的系统中未采用。
