在简要回顾了电子腭图和光学腭图的基础技术之后，本文提出了一种结合电子和光学腭图测量来实时重建发音过程中的舌表面的设备的原型。该原型由一个口件（伪腭）和一个控制板组成，并通过将整个测量系统集成到一个单一的单元中来改进以前的设计，通过更多的传感器来提高空间分辨率，并减少接触伪腭所需的电线数量，以获得更舒适的使用。此外，描述了使用三次样条插值从传感器读数近似和可视化舌头表面的概念。强调了下一个发展阶段的未来挑战。概述的系统可以应用于，例如，实验语音学、言语治疗、无声语音接口和发音训练。
After giving a brief review of the underlying technologies electro-palatography and optical palatography, this paper presents the prototype of a device that combines electrical and optical palatographic measurements to reconstruct the tongue surface during articulation in real-time. The prototype consists of a mouth piece (pseudo-palate) and a control board, and improves on a previous design by integrating the entire measurement system into a single unit, increasing spatial resolution by a greater number of sensors, and reducing the number of wires necessary to contact the pseudo-palate for more comfortable use. Furthermore, a concept to approximate and visualize the tongue surface from the sensor readings using cubic spline interpolation is described. Future challenges in the next development stages are highlighted. The outlined system could be applied in, e.g., experimental phonetics, speech therapy, silent speech interfaces, and pronunciation training.
