2. Language rehabilitation training module:

1) rehabilitation training of non-verbal communication ability: sound and light induction arousal training and touch image assisted communication arousal can be carried out;

2) rehabilitation training of language understanding and expression ability: induction real-time self-feedback training of language can be carried out, including listening training, visual training, voice training, pronunciation organs, oral expression, personalized training, etc.;

Painted 3) speech language comprehensive ability of real-time audio and visual rehabilitation training, feedback, of seeing and hearing feedback training mode, improve children's interest and extend the children's attention, every difficulty function training, can be adjusted according to the different situation of children's obstacle free by pitch, sound changes in real-time, and the size of the sound intensity, the length of the control real-time audio and video game animation awareness training.

4) phonetic training consists of seven parts: vocal training, volume training, length training, tone training, following training, voiced training and vowel track.

5) providing phonetic parameter graph comparison function: using the real-time recording comparison function of teachers and students, real-time display spectrum diagram of tone, tone intensity, tone, etc., and the distinct spectrum comparison function can assist the rehabilitation teachers to quickly and intuitively understand the status of impaired children's speech disorders.

3. Personalized training design module:

1) personalized design: according to the actual needs of students, personalized learning programs can be designed in the corresponding platform, and intensive individualized training can be conducted in each stage.

Painted 2) open platform Kang Fushi according to different patients' actual language level, practical teaching environment, design, edit, rehabilitation training topic, contains the commonly used retelling, naming, judgment, comprehension, reading, set of words, rehabilitation, Kang Fushi can add, select, enter named images, input prompt voice, text input prompts to complete about the rehabilitation training in patients with a training, so as to improve the effectiveness and efficiency of training.

3) dual-screen display technology: in order to ensure the independence of function and operation of both subjects and subjects, the dual-screen display mode greatly enhances the objectivity of evaluation.

4. Student file management module:

1) data management includes: management includes data registration, data modification and data query, which can realize data search, modification, deletion and statistics, and provide multiple parameter fuzzy query functions.

2) print and save data and evaluation results: the evaluation results can be printed and saved at any time, ensuring the security of data.
