Abstract	Reviews a task-dynamic model for coordination and control of speech articulators. An extension of this model is described in which invariant speech units are identified with context-independent sets of parameters in a dynamical system having 2 functionally distinct but interacting levels. The intergestural level is defined according to a set of activation coordinates; the interarticulator level is defined according to both model articulator and tract-variable coordinates. Coproduction effects in speech are described in terms of blending dynamics defined among a set of temporally overlapping active units; relative timing of speech gestures is formulated in terms of serial dynamics that shape temporal patterning of onsets and offsets in unit activations.
