The biggest difference between an audio book and a traditional book is that it is a book that can make sounds. Therefore, children can study without their parents. As long as you click on the words, pictures and game icons in the audio book with a reading pen, you can hear the corresponding words reading, character dialogue, birds singing and insects singing, children's songs music, game quiz and so on. Just like someone telling a story vividly and watching cartoons, their understanding effect and reading pleasure have been greatly improved compared with traditional children's books.
