发音培训研究产生了有关视听（AV）信息（L2）学习者的重要信息。在当前的研究中查看自己的语音表达过程的作用。在语音训练实验中，使用了基于电子关节摄影的互动3D舌头可视化系统（EMA）。在使用运动型（舌头尖端的空间定位）评估自己的语音动作之前，在试验之前，之后和试验之后声音（爆发光谱）的结果表明，与视觉反馈训练相关的准确性很快。
Pronunciation training studies have yielded important information concerning the processing of audiovisual (AV) information. Second language (L2) learners show increased reliance on bottom-up, multimodal input for speech perception (compared to monolingual individuals). However, little is known about the role of viewing one's own speech articulation processes during speech training. The current study investigated whether real-time, visual feedback for tongue movement can improve a speaker's learning of non-native speech sounds. An interactive 3D tongue visualization system based on electromagnetic articulography (EMA) was used in a speech training experiment. Native speakers of American English produced a novel speech sound (/ɖ/; a voiced, coronal, palatal stop) before, during, and after trials in which they viewed their own speech movements using the 3D model. Talkers' productions were evaluated using kinematic (tongue-tip spatial positioning) and acoustic (burst spectra) measures. The results indicated a rapid gain in accuracy associated with visual feedback training. The findings are discussed with respect to neural models for multimodal speech processing.
