      Semi-vowel

      半元音

       

      A term used in the classification of consonant sounds on the basis of their manner of articulation: it refers to a sound functioning as a consonant but lacking the phonetic characteristics normally associated with consonants (such as friction or closure); instead, its quality is phonetically that of a vowel; though, occurring as it does at the margins of a syllable, its duration is much less than that typical of vowels. Some phoneticians refer to these sounds as a type of approximant.

       

      按發音方式給輔音分類的術語,指這樣一類音:功能上類似輔音但又缺乏通常與輔音相聯系的語音特點(如摩擦或閉塞),而語音學上講其音質為元音音質,但由于實際出現在音節的界音位置,其音延要比典型的元音短得多。有的語音學家視這類音為無摩擦音的一類。
