(1) Listening training: It is the process of making deaf children know, pay attention, distinguish, remember, understand and form concepts repeatedly. It consists of three parts: sound stimulation, music stimulation and sound discrimination training.

(2) Articulation training: Deaf children can't pronounce as normal as normal children because of hearing impairment, and generally have problems with articulation. Pronunciation training can help deaf children understand pronunciation essentials, master pronunciation skills, cultivate correct attention habits, and lay a solid foundation for them to speak every word clearly and fluently. Pronunciation training can be divided into the following eight parts: breathing training, tongue training, mouth training, nose training, pronunciation training, phoneme training, pinyin training and four-tone training.

(3) Language training: including the training of comprehensible language and expressive language. Understanding is the basis of expression, and understanding precedes expression.

(4) Adjustment of language environment: Adjusting children's language environment according to their age and development stage can effectively apply the language skills acquired through training in daily life, and can form richer language skills through various activities.
