本文提出了一个动画的2D发音模型的舌头和嘴唇的生物反馈应用。该模型是由实时optopalatographic测量的位置，上唇和舌头在前口腔控制。该测量系统是对先前原型的改进，具有更高的空间分辨率和增强的近距离行为。通过线性预测将舌的后部添加到模型中。预测系数的确定和评价使用语料库的声道痕迹的25个持续的音素。该模型代表了舌头的运动和嘴唇开放的生理上合理的实时发音过程中。索引术语：optopalatography，glossometry，线性预测，动画声道模型，生物反馈
This paper presents an animated 2D articulation model of the tongue and the lips for biofeedback applications. The model is controlled by real-time optopalatographic measurements of the positions of the upper lip and the tongue in the anterior oral cavity. The measurement system is an improvement on a previous prototype with increased spatial resolution and an enhanced close-range behavior. The posterior part of the tongue was added to the model by linear prediction. The prediction coefficients were determined and evaluated using a corpus of vocal tract traces of 25 sustained phonemes. The model represents the tongue motion and the lip opening physiologically plausible during articulation in real-time.
