System introduction: auditory rehabilitation training system is to provide corresponding rehabilitation training for auditory impairment and auditory speech impairment through real-time detection and processing of auditory speech signals. The auditory rehabilitation training system is guided by the internationally accepted theories of the four stages of auditory development (listening and observing, listening and distinguishing, listening and recognizing, listening and understanding). It combines detailed, scientific and rich visual and auditory materials organically, and is equipped with professional, vivid and interesting visual feedback animation to strengthen the auditory rehabilitation of special students.

Scope of application: it is applicable to children with hearing impairment, language retardation, mental retardation, autism, cerebral palsy and other groups with hearing impairment or accompanying hearing impairment. It can be used in rehabilitation institutions of disabled persons' federation at all levels, special education institutions at all levels, and various rehabilitation training institutions.

System function parameters:

1. Clear listening and awareness training of main frequency characteristics;

2. Audiovisual training of filtering compound sound;

3. Auditory resolution training under the condition of supra-segmental resolution;

4. Phonemic recognition training based on phonemic comparison;

5. Auditory comprehension training based on single, double and triple conditions, phrases and short sentences;

6. Identify and evaluate phonemes based on phonemes comparison, and display error trend analysis;

7. Listening and understanding training based on single, double and three conditions, phrases and short sentences;

8. Formant synthesis function: the input speech signal can be analyzed, and the final synthesis formant analysis diagram and simulated sound channel shape diagram can be obtained.

9. Whole-process monitoring system of rehabilitation effect: a single subject technology is adopted to monitor the entire rehabilitation effect.

10. The evaluation results of different times of the same user can be compared and counted, and histogram can be displayed.
