A two-and-a-half-year-old baby who does not speak is considered to have a speech delay. The goal of training for delayed speech and language is to promote the child’s speech and language development and to maximize language skills. The starting point for training is the beginning of the child’s language development, and the training should be extended in two ways. The first is the horizontal development of the same stage, e.g., the child can understand some of the nouns and then further expand the understanding of the nouns. If the horizontal development reaches a certain level, then the next stage can be aimed at training the understanding of verbs, and the training should be applied and consolidated in life as much as possible. In addition, creating a good language environment is one of the keys to improving language skills. Before training, you need to remove the hearing impairment.
