制作了嘴唇的物理模型。在以往的研究中，舌头模型由舌内肌和舌外肌组成，使用粘弹性材料聚氨酯橡胶凝胶。此时，与其他重要的语音发音器一样，上唇和下唇使用聚氨酯橡胶凝胶建模。此外，还利用塑料克雷格制作了一个活动颚模型。将嘴唇模型放在下颚模型上。由于嘴唇模型是由类似人类皮肤的粘弹性材料制成的，因此可以通过手拉动或移动嘴唇和下巴来模拟嘴唇和下巴的语音发音，从而重塑和移动嘴唇。口面肌，如口轮匝肌、提上唇肌、提口角肌、降口角肌、降下唇肌和颏肌被认为是嘴唇运动的关键。该模型可用于语音科学教育或未来基于真实语音产生机制的语音机器人开发。
A physical figure model of lips were made. In previous studies, tongue models consisting of intrinsic and extrinsic tongue muscles were made using viscoelastic material of urethane rubber gel. At this time, as other important speech articulators, upper and lower lips are modeled using urethane rubber gel. Also, a movable jaw model is made from plastic cray. The lips model is placed on the jaw model. As the lips model is made from viscoelastic material similar to human skin, reshaping and moving lips are possible by pulling or moving lips and jaw by hand to emulate speech articulation of lips and jaw. Orofacial muscles such as orbicularis oris, levator labii superioris, levator anguli oris, depressor anguli oris, depressor labii inferioris, and mentalis are considered for lip motions with the figure model. The proposed model is useful for speech science education or a future speaking robot development based on realistic speech production mechanisms.
