The appropriate age condition for speech training is 3 to 4 years old. Normal children during this period can not only repeat the words spoken by adults, but also fully understand the meaning of these words and express their thoughts in simple sentences. The appropriate time to enter speech training after cleft palate surgery is about 1 month, with some functional training in the first 2 months, and speech training after 3 months when the palate scar slowly begins to soften and perception begins to return. Features of speech training Unlike surgical treatment, speech therapy takes 6 months, 1 year or more. When leaving the hospital, during this longer period of time, voice training needs to be performed not only daily, but also with uninterrupted voice stimulation until the patient acquires normal speech. Sequential aspects 1. Steps of voice training Voice training should be done from simple to complex. First, enhance the function of palatopharyngeal closure. (1) Massage. Instruct the patient to use the thumb and massage the palate in the direction of front to back. (2) Make dry vomiting, yawning and loud “ah” sounds. (3) Make the lips, tongue and jaw open, close, gyrate and sway. (4) Increase the air pressure in the mouth. Practice method is: ask the patient to inhale deeply, tightly closed lips, the air slowly inhaled into the mouth, so that the oral cavity full of air, in the oral cavity to increase the air pressure to the maximum, and then open the lips, force the airflow out. (5) blowing training, such as blowing soap bubbles, candles, balloons, harmonica, bubble gum, etc. Containing water gargle, gargle repeatedly before and after meals every day, both so that the soft palate to get functional exercise and can develop good hygiene habits. 2, the order of phonetic training: phonemes → syllables → phrases → phrases → natural communication or dialogue. In the corrective training of phonemes, we can start from the consonant sounds that are easy to observe, imitate and identify, such as the double-lip air-fed blast sounds: Р, Т, K, which can be used as the target sound for early training, because it is used to control the pronunciation airflow with both lips, and its air-fed blast sound has strong airflow along with the spray. For example, when pronouncing the “a” sound, open your mouth as wide as possible; when pronouncing the “” sound, spread the corners of your mouth as hard as possible and grin; when pronouncing the “f When pronouncing the “f” sound, use the upper lip to bite the lower lip lightly. Let the child clearly see the relationship between the change of mouth shape and the sound you make when pronouncing, and through imitation practice you can often master these pronunciation actions quickly. When training the pronunciation of letters, try to extend to the pronunciation time of each vowel, for example: practice the consonant-vowel syllable dragging: pa…, pu…, pi…, practice the combination of consonant and vowel: b-a→ba, d -3. Comprehensive training After the child can correctly pronounce phonemes, further syllable and phrase training should be conducted so that the child can correctly master the sliding of consonants to vowels, and when most syllables and phrases can be pronounced accurately and quickly, short sentences and short essays should be added. For preschool children, let him practice children’s songs and short stories repeatedly, correct the wrong pronunciation in time, with slow and accurate pronunciation, and gradually change to normal speed. Ensure the continuity and stability of training The formation of phonetics is a conditioned reflex process, and time is an indispensable factor to form the condition. Once you start to train your voice, you should insist on it, once or twice a day for 0.5 h~1 h, for more than half a year. As long as you have the determination and perseverance to follow the correct method, most children can get good results. The traditional training method is based on home training, with regular instruction by a speech therapist, which is economical and does not require special equipment or hospitalization.
