How can I do this in my book?

Book Builder has features built right in to help you provide alternatives for visual information.

Whenever you upload an image, Book Builder prompts you to inlcude an alternate description as well as a caption.

Click here to see how one author embeds alternate descriptions and captions for every image in his book.

And, text-to-speech is now available via the TextHelp Toolbar on each page! Select the text you want to hear aloud and click the right facing, green triangle. Or, depress the first button on the left, and double click each sentence you want read aloud. Use the square, red button to stop the reading. Place the toolbar where you like, and it will stay there. Try it out on this page!

Finally, you could make your own audio recording of each page and upload it. Click here to see a book that has the text recorded on every page with some sounds effects as well!
