title_body: How to sync mp3 audiobook to mobi ebook on Kindle for Android? I installed Kindle for Android in my phone.
  I have ebook in mobi format and mp3. The mp3 is an audiobook for the ebook.
  I have put the mobi and mp3 in the Kindle folder. The ebook can read but how do I play the mp3 together and sync with the text?
upvoted_answer: If you would like to have the audio match the text then you would have to create a read aloud ebook using EPUB 3.  You can learn more about this at this link
