ABSTRACT:
Teaching devices are provided which include a transparent element simulating a human head and movable elements simulating articulating organs such as a lower jaw, front and rear portions of a tongue and an uvula, such movable elements being connected to control rods which are manually operable to place the movable elements in positions normally used to produce particular sounds. In addition, elements of elastomeric material having spiral springs cast therein are provided and are operable through tensioned wires for simulating the larynx and lips and positions thereof. A cassette carrying an endless magnetic tape is insertable into a slot in the device and a reproducing head is positioned for cooperation with any selected one of a plurality of tracks on the tape to reproduce a sound corresponding to the positions of the movable elements.
