      Resonance

      共鳴

       

      A term derived from the physics of sound, and used in acoustic phonetics to refer to those vibrations of air movement in the vocal tract which are set in motion by a source of phonation. The main resonance chambers of the vocal tract are the mouth, nose and pharynx, and these cavities, in their various shapes, act to strengthen some of the frequencies present in the source of sound, producing the range of human sounds.

       

      原為物理聲學術語,聲學語音學用來指由一發聲源引發的聲道內的氣流振動。聲道的主要共鳴腔有口腔、鼻腔和咽腔,這些腔以其不同的形狀起到加強音源處某些頻率的作用,從而產生一系列人類語音。
