How a 8 years old boy can speak who hear but not speak?

It's wonderful that you're thinking about how to help someone! It sounds like you're asking about a child who can hear but can't speak. This is a common question, and there are a few things to consider:

* There are many reasons why someone might not be able to speak. Some children might have a condition that affects their ability to speak, like a speech delay, autism, or cerebral palsy. Others might have had a physical injury or illness that affects their speech.

* It's important to remember that every child is different. What works for one child might not work for another. The best way to help a child who can't speak is to work with their parents, doctors, and therapists to find the right approach.

Here are some things that you can do to help a child who can't speak:

* Be patient and understanding. It can be frustrating for a child who can't speak to communicate their needs.

* Use visual aids. Pictures, signs, and other visual aids can help a child understand what you're saying.

* Use simple words and phrases. Avoid using long, complex sentences.

* Give the child time to respond. Don't rush them or get impatient.

* Focus on building a positive relationship. Encourage the child to feel loved and supported.

Remember, even if you can't understand everything the child is trying to say, you can still show them that you care.

If you have any further questions about a specific child or their condition, it's best to speak to their parents or healthcare professionals. They will be able to provide the most helpful information and support.
