One of the more complex acoustic scenarios of basic phonetics begins quite simply, with the opening of the velopharyngeal port (“VP”) to allow the nasal cavities and sinuses to participate directly in the spectral shaping of speech sounds. Through this simple valve operation, or through some other structural anomaly such as cleft palate, a “side-bar” resonant cavity is “coupled” (sharing acoustic energy) with the primary pharyngeal and oral cavities of the vocal tract. The main purpose of this article is to introduce to readers some of the more abstruse, but essential, concepts and terms of physical acoustics for source readings in the acoustics of nasality. It is, therefore, oriented to scholars and practitioners who may have at some point been rebuffed by the “lingo,” but are nonetheless motivated to pursue such studies (with no slight intended to that significant group of Division 5 affiliates already conversant with such materials). As already exemplified in this paragraph, the key concepts that may require some orientation or reintroduction will be boldened.
