An articulation training method for children with hearing disorder was proposed based on a visualization tongue model. By training on the position of articulation for children who have residual hearing and hearing compensation, these children could acquire the accurate place and way of articulation. A tongue three dimensional model was established based on the tongue rehabilitation training with the combination of three-dimensional modeling technology and sensor technology. The three-dimensional positions of tongue during the process of articulation was acquired by a palate sensor. Then, 23 initial consonants were selected as samples for establishing a sample database of tongue positions of children with normal hearing during articulation. Such the tongue model could be activated to provide a guidance for children with hearing disorder during training on the position of articulation. This method displays the movement of tongues of children with normal hearing during articulation and overcomes the shortcomings that has been neglected in tongue training and language training. Experimental result indicates that this method improves the effect of articulation training for children with hearing disorder and shortens training time. Especially for those articulation processes involving complicated coordination between tongue, lower jaw and unobvious position of articulation, the method increases the accuracy of articulation training by 15%.
