Hello, teacher, I have a big tongue. I will graduate from college soon. It’s very painful. I’ll ask you for advice.

After graduation, you will start looking for a job. Big tongue can be trained to speak fluently.

"Big tongue" is a common name for the phenomenon of mispronunciation. Academically, we generally call it dysarthria.

A phoneme is the most basic unit of speech. A phoneme corresponds to a pronunciation action. Since it is an action, it is inseparable from muscle function. For example, the reason why Mr. Hawking, who just passed away some time ago, could not speak during his lifetime, It was because he had a disease that almost completely disabled his muscles.

Each language has dozens of basic phonemes, that is, dozens of pronunciation movements, which require high accuracy. In fact, it can be regarded as an "advanced skill". Like many movements that require skills, they require muscle coordination. The strength must not only be sufficient, but also the control of the force must be fully grasped. This is not simple. Maybe it is just like this. The most suitable stage of development and perfection is to accompany it. It depends on the development of the brain and the development of thinking and cognition. Otherwise, once you are five or six years old, it will be difficult to make complex and changeable pronunciation movements.

We just don’t realize how difficult it is when we first learn to speak, because we don’t remember it at all.
