The treatment of not being able to speak can be done through the use of hearing aids, cochlear implants, speech rehabilitation training, etc. If the child is already 2-3 weeks old and still can’t speak, you should take the child to the hospital in time for a hearing-related checkup. Because some children are severely deaf, there is no way to practice speaking because they cannot hear the sound. Deaf children should be given hearing aids as soon as possible so that they can learn language through their residual hearing. However, the process of learning language may be difficult and some children may not even be able to learn. In addition, after the child is given hearing aids, a cochlear implant can be done when the child is 2-3 weeks old, which can be therapeutic. After the surgery, the child can be given speech rehabilitation training. Besides that, if the child’s hearing is normal but the child doesn’t speak when examined in the hospital, it can be considered that it is caused by autism, or by psychological and mental illnesses, and it needs to be given rehabilitation training in the hospital in order to achieve therapeutic effects.
