Selective Display of Pronunciation Guides in Electronic Books

Techniques for selectively and dynamically determining an amount of pronunciation guides to display within an electronic book based at least in part on an aspect of a user. For instance, an electronic device rendering an electronic book may determine whether to display some, all, or no pronunciation guides for characters within the electronic book based on a reading level of the user, an age of the user, a primary language of the user, or any other aspect that indicates the user's proficiency in the language of the electronic book.
