Audio books are recorded versions of written works, such as novels or non-fiction books, that are meant to be listened to rather than read. They typically come on CDs, cassettes, or digital formats and are narrated by a professional voice actor. Audio books can provide an enjoyable way for people with visual impairments, dyslexia, or other reading difficulties to access literature, as well as offering a convenient alternative to traditional reading for those who prefer listening to reading. They also have the added benefit of being able to multitask while listening, such as driving or doing household chores.
