14. A system for creating a custom narration for a book, the book comprising text, the system comprising: one or more processors; a data store, storing an electronic representation of a narration, the electronic representation including a first portion and a second portion that, during playback, immediately follows the first portion; and a correlation module, communicatively coupled to the data store and the one or more processors, configured to determine, using the one or more processors, a first correlation between the first portion and a first segment of the text, and apply, responsive to the second portion not corresponding to a second segment of the text that immediately follows the first segment, a correlation algorithm to determine a second correlation between the second portion and a component of the book, applying the correlation algorithm comprising: responsive to determining the second portion is a repeat of the first portion, identifying the first segment of the text as the component of the book; responsive to determining the second segment of text is spatially proximate to an illustration, identifying the illustration as the component of the book; responsive to determining the first segment of the text is immediately followed by a chapter break, identifying the chapter break as the component of the book; and responsive to determining the second portion corresponds to a third segment of the text that follows the second segment of the text, identifying the third segment of the text as the component of the book.
