Children's pronunciation is variability, and even the abnormal sound is sometimes unstable. For example, when it is "very short", it is very good, but when it is said that "the younger brother" is unclear, that is, the type of error is affected. The combination of different voices or the influence of different word content structures will have different performances. Generally speaking, the situation of twisting sounds is more common, which means that the child may always send that sound in that way. Omissions and alternatives lack consistency.



1. Factors of the organ of sound organs: It means that the abnormal sound structure is caused by identifiable defects in the organ, such as cleft lip and palate, the tongue is too short, the tongue is too big, the bite is inappropriate, and the hearing is impaired. Muscle and nerve movement coordination disorders, etc., may cause abnormal sound formation. However, there is no absolute proportional relationship between the defects of the articulated organs and the abnormalities of the articulation. In fact, as long as the method of sound formation can be properly adjusted, the voice may still be normal, but the organ is completely normal. When the articulation method is incorrect, it will cause an abnormal sound.

2. Intelligent factors: Infancy to preschool is the most important period of language development, and also a key period for the development of voice-forming ability. If the lack of intelligence is lack of learning ability, it is easy to influence the development of voice-forming ability.

3. Personality characteristics and emotional factors: In general, slow-moving people speak slowly, people with irritable personality speak fast, and speaking quickly is naturally prone to abnormal sound formation. In addition, due to the excessive protection of parents, the child's emotional maturity is hindered, which will keep the child's child language for a long time.

4. Poor learning objects: children's parents, brothers and sisters or other playmates, there are serious phonological abnormalities, children and he have developed a habit for a long time, resulting in bad posture.

5. Environmental factors: From the time of the baby, the child can gradually learn the voice of the language by listening to the mother repeatedly repeating some words, and some children will be given to others from an early age. If the person caring for the child just lets the child lie there and sleep less, then the child will have less chance of receiving language stimulation. In addition, if the parents allow the child to express his or her needs by gestures, and the parents are aware of the childs willingness to meet and satisfy, the language is not important to the child, and naturally there is no willingness to speak in words. The chances of speaking are reduced, and the ability to construct sound is naturally affected.

When children are found to have any of the following dysarthria, they need to be alert to find out the possible causes and early diagnosis and treatment:

First, the baby is too quiet, or lack of reaction to the big voice.

Second, no vocabulary appears until the age of two.

No, three to three years old still have no sentences.

Most of the speech after the age of four or three is still ambiguous.

After five or five years of age, there are still obvious errors in speaking.

After six or five years of age, there are still abnormal rhythms, speeds or intonations in the sentences.

There are still many omissions, substitutions, or distortions in the language of speech after the age of seven or five.

Eight, the voice is monotonous, the volume is too big or too small, or the sound quality is too bad.

9. The voice of the voice is obviously too heavy or lacks nasal sound.

10. The longer you say, the less or less clear you are.


Differential diagnosis

1. Dyphasic disorders include difficulty in articulation and melatony. It refers to a symptom caused by unclear or unreasonable words caused by organic diseases of the nervous system. Common causes include upper motor neuron damage, basal ganglia damage, cerebellar damage, lower motor neuron damage, muscle diseases such as myasthenia gravis, and muscular dystrophy.

2, speech expression barriers. That is, when you want to change the words you want to say (the words in your brain) into voiced words, the dysfunction of the speech organs can not constitute a voice, causing language expression disorders. The light is difficult to articulate, and the heavy one can not be pronounced at all (not for the articulation). Symptoms such as a vocal tendon, small and stiff tongue, accompanied by dysphagia, confusing speech or lip sounds or nasal numbness or soft palsy, can not be pronounced. There are also speech problems caused by brain damage, and the rhythm is turbulent.

3. One of the symptoms of difficulty in pronunciation. It is manifested by the substitution, distortion, omission or addition of phonemes when speaking.
