This paper presents a Virtual Reality interactive three dimensional Mandarin pronunciation teaching model with higher clarity, more friendly interaction and more comfortable user experience. Our system provides four learning modes: initial, final, word and confusion. According to personal needs, learners can switch the demo views, customize visualization of 3D anatomical model’s physiological structure, control play speed of 3D animation, and change position to observe movements and deformations of articulators. Moreover, the system provides assistant pronunciation guidance, such as the pronunciation method, 2D oral section animation, target zone of critical articulators, and contrastive models of confusion minimal pairs to help learners understand the essentials of Mandarin pronunciation.
