Per request, I’m posting snippets of code to use to enable read aloud functionality on an iPad. You usually do this for children’s books in EPUB3. Above is a sample of the SMIL file you will need to include. Remember to make a SMIL file for each “page.” And don’t forget to add it to your OPF! Below is a sample of the extra code to include in the HTML file. You will also need your audio file (use Audacity to easily create labels for the SMIL files). Good luck!
