Children with language delays have problems with language skills that can manifest as expressive language disorders or perceptual language disorders. Expressive language disorder is the ability to understand the language of others, but not to express it completely. Receptive language disorder is a problem in understanding and expressing language and requires systematic training to improve. Therefore, for these children with language delay, the following training methods are usually applied clinically: a. Dysarthria training: Dysarthria is caused by congenital and acquired structural abnormalities of the organ of speech, and can be corrected by two methods of training, namely respiratory training and tongue training. 1. The main method is to let the child perform such actions as opening the mouth, showing the teeth, shutting the mouth, etc. to train the lips and jaw. In addition, ice can be used to stimulate the child’s mouth and to pat the jaw in order to soothe the muscles needed for articulation. 2. tongue training: Under the guidance of a professional rehabilitation physician, tongue training involves regular movements of the tongue in the mouth to make the tongue flexible. Language delay training: 1. Game therapy: Attracting the child with interesting games can make the training easier. Through games, children can improve their responsiveness to the outside world and apply the vocabulary they have learned. 2. Gestural symbol training: For children with severe language delay, gestural symbols can be used as a way to introduce expression training and gradually transition to language. 3. Word training: For children with language delay, words can be a good alternative means of expression. It is suitable for children with delayed language comprehension and expression, and children with good language comprehension but difficulty in expression. 4. Some children may have medical conditions that prevent them from training, such as hearing impairment or abnormalities in the organ of speech. In order to achieve the best training results, it is recommended that these children go to the hospital to have these factors corrected or improved before training.
