我们最近复制了人类声道的千叶和Kajiyama物理模型，并发现它们作为声学教育的操纵工具非常有效。这项研究是我们以前的发展模式和他们的教育应用的概述。我们开发的模型模拟声道的配置，并且有两种主要类型：圆柱体和平板。圆柱形模型的内部瓶形是基于千叶和Kajiyama的原始测量。板型模型的10-17个可移动板中的孔直径也基于千叶和Kajiyama测量值，但半径曲线以逐步方式近似于10 mm分辨率。我们还开发了一个鼻化模型，它包括一个侧分支连接到一个圆柱形模型。我们的经验证实，在课堂环境中使用时，模型增加了学生的理解语音生产的声学理论。
We recently replicated the Chiba and Kajiyama physical models of the human vocal tract and found that they are extremely effective as a manipulative tool for education in acoustics. This study is an overview of our previous development of the models and their application for education. The models we developed simulate the configuration of the vocal tract, and are of two major types: cylinder and plate. The interior, bottle shape of the cylindrical models was based on the original measurements of Chiba and Kajiyama. The diameters of the holes in the 10–17 movable plates of the plate‐type model were also based on the Chiba and Kajiyama measurements, but the radius curves were approximated at 10 mm resolution in a stepwise fashion. We also developed a nasalized model, which consists of a side branch attaching to a cylindrical model. Our experience confirmed that when used in a classroom environment, the models increase student understanding of the acoustic theory of speech production.
