Language is a special class of higher neurologically active forms in humans and is also an important tool for people to communicate and think. In modern society

the importance of language for communicative competence has increased significantly due to the increasing social and social activities of people. Verbal communication skills are the main form of social adaptation

and linguistic competence is the main determinant of people’s interpersonal interaction. Children with autism are part of the adult population

and therefore educational training for the language communication barriers they face is imperative. However

for children with autism

there are significant barriers to verbal expression because of their brain function. And the severity of language impairment in children with autism can range from a large reduction in words and complex utterances to not being able to speak at all and not understanding language. This chapter will analyze and summarize these current situations and briefly describe some of the author’s experiences in language rehabilitation training.
