For children with delayed speech development, the most important thing is to carry out standardized and professional rehabilitation therapy, and at the same time, parents can be guided by oral muscle training, cognitive comprehension training, oral expression training and other methods. 1. Oral muscle training: Pronunciation is mainly produced by the joint action of the tongue, lips, jaw and other organs. Parents can guide their children through tactile adjustments, tongue motor skills exercises, lip motor skills exercises, etc. to exercise their children’s oral perception and motor skills. 2. Cognitive comprehension training: Children with delayed language development are mostly accompanied by poor cognitive comprehension. Parents can guide their children through fruit cards, animal cards and other cognitive comprehension training to exercise their cognitive comprehension ability. 3. Oral expression training: Parents should communicate with their children anytime and anywhere in their daily lives, gradually transitioning from simple pronunciation to complex phrases to exercise their children’s oral expression skills. It is important to note that home training cannot replace professional rehabilitation. In addition, parents need to be patient and persevere for a long time in guiding their children with delayed speech development. Parents are advised to consult relevant experts to guide their children in a scientific and reasonable way.
