Some considerable time ago, Amazon starting cutting back the text to speech options on ebooks. Very irritating to me, since I liked having my books read aloud. You could still use to text to speech if you were using a browser on a computer, but the option became less available on most of Amazon's apps and devices.
Recently, Amazon's KDP has released a chargeable text to speech audiobook option, with certain minimum pricing requirements on them. So a book that you could normally text to speech after buying the ebook, now has a separate 'audiobook' that is actually just text to speech.
After some debate, I've made these available, but keep in mind that, even with the $0.99 stories, there's a minimum pricing charge for these audiobooks. If you already own the ebook, instead of buying these 'audiobooks', feel free to use a text to speech reader in the Kindle browser version. I've made them available purely for readers who really want to listen to these books on a mobile device, even if there's an extra charge.
But in my view, this move by Amazon is a bit of a rort, and you're best served using existing free text to speech options.
[Note: any of my books that has an existing voiced audiobook is not impacted by these text to speech audiobooks.]
