Resonance

共鸣

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.

原为物理声学术语，声学语音学用来指由一发声源引发的声道内的气流振动。声道的主要共鸣腔有口腔、鼻腔和咽腔，这些腔以其不同的形状起到加强音源处某些频率的作用，从而产生一系列人类语音。
