Oral exercise training: Exercise children's jaws, lips and tongue by licking honey, magic straws and oral muscle exercises, so that children can use the pronunciation organs independently and harmoniously.
2. Listening training gives children a rich listening environment. In daily life or games, we can input language in real time, let them listen, watch and manually, and at the same time receive auditory information with the same meaning, so as to cultivate their listening habits.
3. Communication training uses objects and eye contact to improve communication behavior. For example, in the subject of mosaic training, children who haven't mastered phonetic symbols should match the mosaic daughter board to the motherboard. When children can't operate smoothly, they should be induced to ask a speech therapist for help, or to pull or watch with their hands. These are not the formation of verbal communication behavior, but also the basis of language communication.
