Since you can enjoy reading with just your ears, you can enjoy “reading while doing it” not only for people who have difficulty reading, but also for all kinds of situations in your life, such as while running, while traveling by train or car, or while doing housework. In recent years, the number of audiobook users has rapidly increased due to the rapid spread of smartphones and wireless earphones, which has rapidly improved the environment for the use of audio content, and the introduction of subscription plans that allow unlimited listening to a variety of works for a fixed fee. Currently, audiobooks are becoming the third type of book, following paper books and e-books. [Reference] Learn about audiobook production and recommended works! “Understand everything! Audiobook”
