      Voice-onset Time

      噪音起始時間

       

      A term used in phonetics, referring to the point in time at which vocal-fold vibration starts, in relation to the release of closure. In a fully voiced plosive, for example, the vocal folds vibrate throughout; in a voiceless unaspirated plosive, there is a delay (or lag) before voicing starts; in a voiceless aspirated plosive, the delay is much longer, depending on the amount of aspiration. The amount of the delay, in relation to the types of plosives, varies from language to language.

       

      嗓音起始時間是語音學術語,指繼閉塞開放后聲帶開始振動的時點。例如一個完全帶聲的破裂音,聲帶自始至終振動;一個不帶聲的不送氣破裂音,帶聲開始前有一延遲(或時延);一個不帶聲的送氣破裂音,時延要長得多,取決于送氣的量。各種類型的破裂音時延的長短隨不同語言而異。
