FYI Kindle is in the process of rolling out a new feature that enables read aloud with synchronized text highlighting. It doesn't sound as good as an audiobook, of course, and it's not as good as the Alexa-powered read-aloud. But it's still nice because you don't have to switch between the Kindle app and the Alexa app.

I understand that some users currently have access, and it will be rolled out to everyone in the next month.
