  We present a modular framework for articulatory animation synthesis using
speech motion capture data obtained with electromagnetic articulography (EMA).
Adapting a skeletal animation approach, the articulatory motion data is applied
to a three-dimensional (3D) model of the vocal tract, creating a portable
resource that can be integrated in an audiovisual (AV) speech synthesis
platform to provide realistic animation of the tongue and teeth for a virtual
character. The framework also provides an interface to articulatory animation
synthesis, as well as an example application to illustrate its use with a 3D
game engine. We rely on cross-platform, open-source software and open standards
to provide a lightweight, accessible, and portable workflow.
