What is an Audiobook? An audiobook is a "listening book" where a narrator or voice actor reads a book aloud. Since you can enjoy reading just by listening, it's perfect for those who find it difficult to read text, as well as for "reading while doing" in various daily scenarios such as during runs, commutes by train or car, or while doing housework. In recent years, the rapid improvement of audio content usage environments due to the spread of smartphones and wireless earphones, along with the introduction of subscription plans offering unlimited listening to various works for a fixed fee, has led to a surge in audiobook users. Audiobooks are now expanding as the third form of books, following paper and e-books. 【Reference】Learn everything from audiobook production to recommended works! "Maruwakari!
