In the future, we will develop this application to have the voice to explain all of exercise in application because children can’t use by themselves. If there is a voice explains how to use, they will understand and be able to use it. But we don’t sure that they can use by themselves or not, if there is the voice explains all exercises in application. So we don’t do it yet.
The language in application maybe in English that can use around the world if it can be developed, children in other countries can use this application to prepare for reading too.
