Audible sells the recording
An Audible audiobook is a separate product from the ebook. A narrator records it, a studio edits it, and you buy it, usually with a monthly credit. For a novel you love, that performance can be worth the price.
It does nothing for the books already on your Kindle. Some of them have no audiobook at all, and the ones that do cost a credit each, though you have already paid for the text. We go through every way to hear those books, on a Kindle e-reader and on a phone, in our post on listening to audiobooks on Kindle.
Readio reads the library you have
Readio signs in to your Kindle account and shows your books. Press play and a natural voice reads from your last page, with the screen off if you like. It reads the ebook itself, so a book Audible never recorded is no gap: every book in your library can be heard, apart from comics and picture books (which books Readio can read). A Chrome extension that lights up each word on the Kindle page is coming soon to the Chrome Web Store.
Readio suits non-fiction, older books and Kindle Unlimited titles (Kindle Unlimited is now called Kindle+): books you want to get through. It suits a novel less when you want the story acted.
What three years cost
An Audible membership pays for one new book a month. Readio Pro pays for listening to every book you own.
Audible$538Readio$240Audible Premium at $14.95 a month, which includes one credit a month. Readio Pro yearly at $79.99 a year (Pricing has the weekly and monthly plans). US prices, before tax.
Natural voice or human voice
A good human narrator acts the book: accents, timing, emotion, sometimes a full cast. Readio’s voices do not act a scene. We think they are the best synthetic voices a book can be read in, and they read every book you own, at 0.5× to 3×.
If you want to try, every Readio voice has a short sample you can play before you choose.
Which should you choose?
Pick Readio for
- The Kindle books you already bought
- Books that never got an audiobook
- Kindle Unlimited titles
- Listening with the phone locked, with a sleep timer
- One price for your whole library, not a credit per book
Pick Audible for
- Fiction where the performance matters
- Audible Originals and full-cast productions
- Listening offline, on a plane or underground
- Alexa, a Kindle or a Sonos speaker
You can use both: Audible for the few books worth a performance, Readio for everything else on the shelf.
