      (1) A term used in the phrase source feature to refer to one of the five main dimensions of classification in Chomsky and Halle’s distinctive feature theory of phonology (the others being major class features, cavity features, manner-of-articulation features, and prosodic feature). The term subsumes the feature oppositions of heightened subglottal pressure, voice and strident.

      (2) In acoustic phonetics, source refers to the waveform of the vibrating larynx. Its spectrum is rich in harmonics, which gradually decrease in amplitude as their frequency increases. The various resonance chambers of the vocal tract, especially the movements of the tongue and lips, then act on the laryngeal source in the manner of a filter, reinforcing certain harmonics relative to others. The combination of these two elements is known as the source-filter model of vowel production.

      (3) In the study of communication, source refers to a point of origin of a message, as opposed to its ‘destination’. More specifically, in semantics, the term is used a s part of a localistic theory of meaning: an entity takes a ‘path’ from a ‘source’ to a ‘goal’. In case grammar, it refers to the place from which something moves.

      (4) In historical linguistics, the term is used to characterize a language from which a particular feature (such as a loan word) comes (the ‘source language’); the receiving language is known as the ‘matrix’ language.

      (5) In translating and interpreting, the term describes the language from which a message originates (the ‘source language’); the ‘target language’ is the one into which the translation takes place.

       

      (1)用在短語聲源特征中,指喬姆斯基和哈勒在其音系學的區別特征理論中分出的五大維度之一(其余四個是主要音類特征,腔特征,發音方式特征,韻律特征)。聲源特征包括聲門下增壓、嗓音和粗糙音等特征對立。

      (2)聲學語音學術語,指喉振動時的波形。其頻譜多諧波,隨頻率增高而逐漸降低。聲道的各個共鳴腔,特別是舌和雙唇的運動以過濾器的方式作用于喉聲源,使某些諧波相對其他諧波得到增強。這兩個成分結合起來稱作元音產生的聲源過濾模型。

      (3)研究信遞時“源點”指一個消息的起源,與“終點”相對。語義學中,這一術語具體用于意義的方位主義觀:一個實體取一“路徑”,從“源點”到達“目標”。在格語法中,“源點”指某物移動的開始處所。

      (4)歷史語言學術語,指某一特征(如某一借詞)來自某一語言,這種語言就叫“源語”;接受這一特征的語言稱作“基語”。

      (5)書面和口頭翻譯中,“源語”指某一信息的來源語言;翻譯成的那種語言稱作“目標語”。
