Speech Rehabilitation System for Hearing Impaired Children Based on Virtual Reality Technology

In the field of public welfare, the rehabilitation of hearing-impaired children is widely concerned by the society. Virtual reality technology integrates simulation and electronic information technology, and uses computer to create a simulation environment to immerse users in the environment. This paper introduces a speech rehabilitation system for hearing-impaired children based on virtual reality technology. The system can not only help hearing-impaired children with hearing rehabilitation training, but also reduce the difficulty of rehabilitation training. The system uses virtual 3d animation to reproduce the common communication scenes in daily life, and applies the dialogue in the scene and the pronunciation actions of monosyllabic words in Chinese pinyin to the language rehabilitation training of deaf children. The experimental results show that the systematic simulated pronunciation can effectively simulate the movement of the vocal organs, and can improve the language ability of hearing impaired children in the training process, which has high application value.
