It is too late to say it. He didn't talk when he came, or didn't talk much, or what happened? When a child speaks late, his pronunciation is often unclear, because he is like an aspirated sound and can't pronounce J, Q and X. In the pronunciation stage, some of them need half a year to develop.

But if you pass the developmental stage, his pronunciation may not develop well all his life, which is out of proportion. For example, the pronunciation we are talking about has two concepts, one is production and the other is maturity. Birth means that he can say it unintentionally, but he doesn't know this eight, which is the eight of 12345678. He doesn't know what this father is. It's called making sounds. How many sounds can he make?

Generally speaking, the development of this pronunciation generally refers to mature sounds, not to what sounds he can say, but to mature sounds and sounds he can make. Now someone is doing research, and a table can be made, which may explain, for example, what sounds should be pronounced at the age of two, which sounds are mature, what sounds should be pronounced at the age of three, and which sounds are mature.

A normal child, I think it is best to let him develop naturally from eight months, but the rapid development period of his pronunciation learning should be from eight months to three years old, or even two and a half years old.

There is a stage in the development of his pronunciation. He has a babble with 50 syllables, which is meaningful, from eight months to one and a half years old. By the time he is one and a half years old, the pronunciation he can pronounce and the words he can understand should be about 150. His pronunciation is from monosyllabic to overlapping, mom and dad, playing outside, that's it, and then he can have syllable combinations.

However, it must be remembered that every time a factor is added, his clarity may decrease, and it may decrease a little, because some parents are anxious, saying that the child's original father's vocabulary is quite good, and no one can hear clearly when talking together. He has such a stage, so don't worry too much.

When some of our children came, they said they wanted him to learn this, saying that the children could not speak clearly. I said, what did you let the children learn? When he was two and a half years old, he had a cleft palate, and his brother crossed a wide ditch with a melon basket. He was talking about tongue twisters. I said he should only speak cross talk. He is not at that age of development, so he must master this age.
