Quick Answer

The ability to listen and understand develops before the ability to speak.
What should concern you is not silence, but an environment with no opportunities to speak.

The child readily understands English videos and responds with actions to simple instructions in English. But when asked to speak in English, the child keeps their mouth firmly shut. After years of lessons with nothing being said, parents naturally become anxious and wonder, "Is there something wrong with this approach?" To begin with what should reassure you, it is a natural sequence in language development for the ability to understand to develop before the ability to speak. The same was true of the child's first language. The child understood what their parents said long before they began to speak.

Receptive language and language used for expression are different

Although both involve English, understanding and speaking require different abilities. Understanding means using familiar words and the situation as clues to infer the meaning of sentences someone else has already formed. Even when unfamiliar words are mixed in, context fills in the gaps. Speaking, by contrast, requires the child to choose words directly from their mind, put them in order, and use the muscles of the mouth to produce sounds. Because the child must form a sentence from the beginning without helpful context, even the same level of English requires far more practice. This is why there is a time lag in which understanding builds first and expression follows.

Silence itself is not the problem.
An environment with no opportunities to speak is the problem.

Point 01

Even during a period that appears quiet from the outside, the expressions a child has heard are often accumulating within them. Once enough has accumulated, short words begin to slip out. However, this does not mean that "all you have to do is wait." If a listening-only structure continues for a long time, the child may become stuck in a state where much has accumulated but there is no pathway for bringing it out. So the question parents should ask is not "Why isn't my child speaking?" but "Is there a pathway for speech in my child's daily life?"

Natural silence and stagnation that requires attention are different

The two states look similar on the surface and are easy to confuse, but they can be distinguished by several signs. With natural silence, the range of understanding continues to expand even without speech. The child understands this month a sentence they could not understand last month, and responses gradually increase, even if they are only gestures or single words. By contrast, if the child's level of understanding has remained unchanged for months, the child avoids English itself and appears withdrawn, or there are no opportunities to speak at all, it is difficult to expect time alone to resolve the situation.

Four Signs to Check

Criteria for deciding whether the silence can be observed for now

01

Is understanding continuing to grow?

If the range of what the child understands is expanding even without speech, language is likely developing within them. If understanding has also stopped, it is time to examine the difficulty level and the learning method itself.

02

Are there even small responses?

A nod, a single word, or humming a song is also the beginning of output. If there is no response at all and the child seems to avoid it, you should look at the child's emotional state before focusing on learning.

03

Are there opportunities to speak?

If the child's routine consists only of watching videos and answering listening questions, there is no reason for the child to speak. In such cases, the cause of the silence lies not with the child but with the schedule.

04

Is it safe to make mistakes?

If a child has had their pronunciation criticized or has been compared with other children, the child will choose to keep their mouth shut. In such cases, silence is a defense rather than a stage of learning.

How to

How to Create Pathways for Output

This is different from forcing a child to speak

Start with repeating aloud

Asking a child to form their own sentences from the beginning places a heavy burden on them. Repeating a sentence they have heard has a low threshold because there is nothing to choose or construct, and it develops the muscles of the mouth and a feel for the sounds. Simply imitating a short line from a video or a sentence from an audio recording is enough.

Continue with reading aloud

When a child reads aloud a book they previously read only with their eyes, reading itself becomes speaking practice. Because the content is already familiar, there is little chance of failure, and one or two pages a day is not burdensome. It is best to start with a book that is easier than the level the child can comfortably read.

Establish a brief daily speaking routine

Once a day and one or two sentences are enough. Setting a fixed time and place, such as saying one sentence learned that day before bed, allows the routine to continue without relying on willpower. In speaking, frequency builds ability more than volume, so brief daily practice leaves more of an impact than one long session a week.

Create an atmosphere where it is safe to make mistakes

When a child says an incorrect sentence, first acknowledge that the meaning came across rather than correcting the grammar. Responses such as "That makes sense. I understood you" need to accumulate before the child will try the next sentence. Accuracy often follows after the amount of speech has built up.

The material for speaking ultimately comes from listening. The sequence for building input is covered in Why Listening Comes First, and the principle of how daily repetition builds ability is covered in Daily Learning.

Scenario

What to Do in These Situations

My child answers in Korean when asked in English
This is closer to a positive sign than a cause for concern. Answering in Korean is evidence that the child understood the English question accurately. Accept the answer without correcting it, and simply repeat one key word from the child's answer in English. Forcing the child to answer in English often leads them to avoid the question itself.
My child's listening scores are good, but they do not speak in speaking class
Having to speak in front of several children is the environment with the highest barrier to speaking. First, let the child build experience speaking alone at home by repeating aloud and reading aloud. The child needs to become comfortable speaking where no one is evaluating them before speech will come in class as well.
When I ask my child to repeat aloud, they do it carelessly as if they are joking
Even if the child does it as a joke, the pathway is opening as long as they are making sounds. Instead of demanding a serious attitude, accept imitations in silly voices and keep the child speaking. Once it becomes enjoyable, accurate imitation often follows.
I have waited for months, but there has been no change
This may be a situation in which waiting alone is not enough. Check the four signs above. If understanding has also stopped, the learning difficulty is often unsuitable. If understanding is growing but speech alone is absent, there are often no opportunities to speak. The response differs depending on the cause.
FAQ

Frequently Asked Questions

How long does the silent period usually last?
Variation among children is so great that it is difficult to specify a set period. It is better to look at the direction rather than the duration. If the range of what the child understands continues to expand and responses through gestures or words are increasing, the child is often still within the process even if speech comes late. By contrast, if understanding has also remained unchanged for months, it is time to examine the learning environment regardless of the duration.
Should I make my child speak even if I have to force them?
Pressure usually backfires. When the pressure to speak is repeated, children often begin to avoid English itself. Instead, it is better to begin with forms of speaking that have a low threshold. Activities with little chance of failure, such as repeating sentences the child has heard and reading a familiar book aloud, help the child begin speaking without pressure.
Should I leave pronunciation or grammar mistakes uncorrected?
Before speaking becomes established, it is best to limit correction. When corrected every time they make a mistake, children often respond by speaking less. First acknowledge that the meaning came across. For expressions you worry may become ingrained, a safe approach is for the parent to restate them naturally in a correct sentence instead of pointing out the mistake.
Will video English lessons help my child begin speaking?
They can help by creating opportunities to speak. However, placing a child who has almost no experience speaking alone directly into a conversation with a stranger can create a heavy burden and may backfire. A reasonable sequence is to first practice opening the mouth through repeating aloud and reading aloud, then add interactive lessons when the child is ready.
