Physical models of the human vocal tract with gel-type material
Abstract: Beginning in 2001, we have been developing models of the vocal tract to promote a more intuitive understanding of the theories for speech science for technical and non-technical students. In this paper, we compared and contrasted four newer models of the talking heads: our original model with a gel-type tongue, a similar model including teeth and palate, a third model with teeth and palate having a default low tongue height, and a fourth ultra-malleable model made completely of gel material. Results are discussed regarding their strengths and weaknesses for educational purposes and articulatory training in speech pathology and language learning.
