      Transition

      1)過渡[]

      2)過渡

       

      (1) A term used in phonology to refer to the way adjacent sounds are linked. There are many ways in which the relationships between successive articulations may be described: one general classification which has been suggested distinguishes between close transitions and open transitions, similar to the distinction between close and open juncture. Close transitions refer to those articulations where there is an articulatory continuity between successive sounds; in open transition, by contrast, there is a break in the continuity of the articulation. The distinction can be seen in the s-s sequences heard in this sort and this assortment, where the former illustrates a close and the latter an open transition.

      (2) The term is also used in acoustic phonetics for the acoustic change which takes place as the vocal organs move to and from the articulatory positions of consonants, especially plosives. The transitional features, or transients, can be clearly seen on a spectrogram, by the way the formants of the adjacent vowels are bent upwards or downwards, depending on which consonant is articulated.

       

      (1)音系學用來指兩個相鄰的音互相聯系的方式。兩個相繼發音動作的聯系可用多種方式來描寫:一種大體的分類是區分閉過渡和開過渡,類似于閉音渡和開音渡的區分。閉過渡是指相繼兩個音之間發音上是連續的,而開過渡則在發音上有中斷;例如s-s序列,在this sort“這一種”中是閉過渡,而在this assortment“這種分類”中是開過渡。

      (2)聲學語音學用來指發音器官在輔音的發音位置來回移動時產生的聲學變化,特別見于破裂音。過渡特征可從頻譜上明顯看出,即相鄰元音的共振峰朝前或朝后彎曲,取決于發的哪一個輔音。
