Conclusion: “The geometric information such as cross-sectional area and the volume of the vocal tract can be obtained using the [Eccovision] Acoustic Pharyngometer. The accuracy of this device is verified during this research and is found to be satisfactory. The Pharyngometer is extremely cost effective as compared to MRI for vocal tract analysis. Hence using parametric techniques to create models for other subjects will be extremely beneficial.
Researchers looking to study the vocal tract dimensions during various human speech conditions can create the particular solid model by getting the cross-sectional areas through the Pharyngometer using Rapid Prototyping. Hence this method provides researchers a variety of models they can choose from.”
