A manipulative tool for demonstrating the relative positions and configurations of articulators and other oral structures, when making phonetic sounds. The tool comprises a tongue, upper and lower palate, and upper and lower teeth, as well as, adjustable and positional lips, any one of which may be manipulated and posed so as to retain placement once released by a user. In this regard, the manipulative tool is used to demonstrate proper formation of certain phonetic sounds to assist in speech therapy or training of persons who are affected by speech impediments, or to assist in the training of future clinicians.
