Readio or Kindle’s own read-aloud? Amazon may already read your book to you
Amazon has several ways to hear a Kindle book: Assistive Reader in the Kindle app and on newer Kindles, Alexa, VoiceOver on iPhone, and Audible narration with Read & Listen. Most of them are free. Here is what each one does, and where Readio is different.
Readio or Kindle read-aloud: which should you use?
Kindle’s Assistive Reader is free and lights up the text as it reads, but it works only on books with Enhanced Typesetting, in your device’s voice. Readio reads every Kindle book in your library in natural AI voices, on iPhone, Android and in Chrome. Use Amazon’s if it reads your book; choose Readio for the rest.

What Amazon offers
Assistive Reader in the Kindle app. The free Kindle app for iPhone, iPad, Android, Mac and Fire tablets can read a book aloud with your device’s own text-to-speech voice. Turn it on in the book’s Aa menu, under More. The text lights up as it is read, and you can change the speed. It works only with books that have Enhanced Typesetting, in a language your device’s voice supports, and it pauses when you open the menu or make a highlight or note.
Assistive Reader on a Kindle. The same feature is on Kindle e-readers from the 11th generation, Kindle Scribe and Kindle Colorsoft. It reads books in English, Spanish, French, German and Italian, again only with Enhanced Typesetting, and highlights the words as it reads.
Alexa. Kindle Assistive Reader also works on Alexa built-in devices, in Alexa’s voice. You ask for a book by name, skip by chapter, change the speed and set a timer, all by voice. Amazon made it for customers with disabilities. It needs Enhanced Typesetting and one of Alexa’s languages, and it is not available on Alexa+.
VoiceOver on iPhone. The Kindle app works with Apple’s VoiceOver screen reader. With VoiceOver on, a two-finger swipe down reads the book continuously and turns the pages. Amazon says audio support covers “many books”. On Kindle e-readers, Amazon’s VoiceView screen reader is there for blind and low-vision readers.
Read & Listen. This is the new name for Whispersync for Voice. If you have both the Kindle book and the Audible audiobook, you can switch between reading and listening, and Immersion Reading lights up the text as the narrator reads. It is a person, not a computer voice, but you need the audiobook for each title. We compare that in Readio vs Audible. Which Kindle e-readers play Audible audiobooks, and what they need to do it, is in listening to audiobooks on a Kindle.
Where Amazon is ahead
Amazon’s read-aloud is free and already in the app you use. It runs on more devices than Readio, including Kindle e-readers, Fire tablets, Mac and Alexa speakers. And with Read & Listen you can have a human narrator on the same book, which Readio does not do. If Assistive Reader works on your book and its voice suits you, start there.
Where Readio is different
Amazon’s Assistive Reader reads only books with Enhanced Typesetting. Readio reads every Kindle book in your Amazon library, including Kindle Unlimited, so a book without Enhanced Typesetting can still be read. A few kinds of book are out, such as comics: see which books Readio can read.
The voice is the other difference. Amazon uses the voice your device or Alexa already has. Readio uses natural AI voices, with 40+ to choose from. Readio also reads in the Kindle web reader in Chrome and lights up the spoken word there, and on the phone it keeps reading with the screen locked, with a sleep timer and controls on the lock screen.
Readio needs a connection to make its voice, so it is not for listening offline.
What it costs
Amazon’s read-aloud costs nothing beyond the book: it comes with the Kindle app, a Kindle or an Alexa device. Readio Pro is $9.99 a week or $79.99 a year in the US, or $24.99 a month on the web, and one plan works on iPhone, Android and Chrome. There is no free trial in the apps. In Chrome, a free account listens with the computer’s own voice. So try Amazon’s first, and pay for Readio only if the book or the voice isn’t right for you.
Which should you choose?
Pick Readio for
- Every Kindle book you own, not only the supported ones
- Natural AI voices you can choose from
- Reading along in the Kindle web reader, word by word
- Listening with the phone locked, with a sleep timer
Pick Amazon’s read-aloud for
- Books with Enhanced Typesetting
- Listening on a Kindle, a Fire tablet or an Alexa speaker
- A free option, when the device voice is good enough
- A human narrator, with Read & Listen
You can use both: Amazon’s read-aloud where it works, Readio for the rest of the shelf.
