X-tier
X-音层
A term used in autosegmental phonology to describe a conception of the skeletal tier in which the feature [syllabic] is eliminated, segments being specified for no features at all, thus contrasting with the CV-tier approach; also known as the timing unit or timing tier theory. This approach is claimed to have advantages in removing redundancy (the overlap in function between syllable position and whether a position is a C or a V).
自主音段音系学术语,用来指[成音节]特征被消除的骨架层,这个音层上音段没有指定任何特征,因而与CV-音层模型相对立;也称作时标单位或时标音层理论。这一理论的长处据称在于能取消羡余(音节位置和一个位置是C还是V,这两者在功能上的部分重叠)。
