The package enables the user to visualise the vocal tract. The vocal tract (in the package) is manipulated by a vector of articulation parameters according to the S. Maeda model. Animation may be achieved by providing a sequence of vectors over time (e.g., from Matlab). A sequence of vectors for certain German phonemes is embedded in the package, which allows for animation when no other vector is available.

The package’s graphics are produced using pstricks.
