Patients, parents and teachers of deaf children should be made aware of the importance of post-operative cochlear implantation auditory language rehabilitation training, especially the preparation of pre-speech deaf children for post-operative rehabilitation training and the choice of rehabilitation sites. Pre-operative rehabilitation training should be tailored to the age and level of hearing and language of the child, and should focus on the establishment of auditory awareness and the understanding of the definition of concepts, in order to prepare the child for post-operative start-up and rehabilitation training. The “Auditory Oral Training Method” is a logical and strict guideline. For children with cochlear implants, it refers to the use of the cochlear implant signal to maximize the development of hearing, followed by the development of oral language, creating the best possible environment for the child. Auditory speech training for deaf children should be conducted in accordance with the rules of language development in children and in stages from superficial to profound according to the “hearing age” of the child. There are three stages: auditory training stage, vocabulary accumulation stage, and language training stage. The main purpose of the auditory training stage is to use the deaf child’s residual hearing to listen to various sounds, to awaken the “sleeping state”, and to give frequent stimulation, repeated training, and repeated reinforcement, so that the deaf child gradually adapts to various daily sounds and enters the audible society; 2. The stage of language training is based on the accumulation of vocabulary, training deaf children to speak more, from single words to short sentences, from simple to complex, from less to more, so that they can gradually understand other people’s language, so that others can understand their own language. Cochlear implant rehabilitation should be implemented under the guidance of professionals, and services that undertake professional rehabilitation guidance provide appropriate rehabilitation training models for hearing impaired children and families.
