The objective is to present a formalism which offers a framework for several articulatory models and notions such as targets, gestures and the quantal principle of speech production. The formalism is based on coupled differential equations that relate the vocal tract shape to its eigenfrequencies. The shape of the vocal tract is described either directly by means of an area function model or indirectly via an articulatory model. Possible synergetic relations between phonetic gestures or targets and the quantal principle of speech production are discussed.
