Popular type of “reading” alternative made from recordings of spoken words.

“An audio book is a recording of the contents of a book read aloud. It is usually distributed on compact discs (CDs), cassette tapes, or digital formats (e.g., MP3 and Windows Media Audio). The term “audio book” has been synonymous with “books on tape” for roughly 20 years. Cassette tape sales still comprise roughly 40% of the audio book market, with CDs the other dominant format type.” (From Wikipedia)
