The 3D Face Feature Extraction and Driving Method on Pronunciation Rehabilitation for Impaired Hearing

The 3D conversation based pronunciation rehabilitation method for impaired hearing children is a new visual teaching auxiliary technology, which overcomes traditional teaching model and is used more widely. The key techniques are extracting 3D facial features and driving 3D head models. To solve the existing problems about traditional methods, the paper proposes a kind of 3D face feature extraction method and driving method suitable for pronunciation rehabilitation of impaired hearing children. This method has been applied to the pronunciation rehabilitation training system. Experimental results show that the method enhances the accuracy of the feature extraction and has a strong anti-interference ability.
