In this study, we constructed a neuro-computational model by refining the previous physiological articulatory model as a peripheral organ model, where a mapping was established between high-level motor representation to low-level motor representation. The neuro-computational model was confirmed by simulating the speech learning in babbling stage. The results of the vowel learning experiment imply that when perceiving an unfamiliar speech sound, subjects seem to build up a virtual target by projecting the sound to their own acoustic space of the native language, and then approach the target during the learning process.

在这项研究中，我们通过将先前的生理关节模型改进为外围器官模型来构建了一个神经计算模型，在该模型中，在高级运动表示之间建立了映射到低级运动表示。神经计算模型通过模拟言语学习的阶段来证实。元音学习实验的结果表明，当感知不熟悉的语音语音时，受试者似乎通过将声音投射到自己的母语的声学空间中，然后在学习过程中接触目标。
