You can essentially turn your Kindle content into audio content on most recent generations of Kindle Fire tablets, using the Text-to-Speech feature. If Text-to-Speech is an option on an e-book, you should see a note saying “Text-to-Speech Enabled” next to the book on the product details page. So look for that when you’re shopping titles in the Kindle book store. It’s also possible to use the Text-to-Speech feature to read personal documents, like those that you create yourself and then load onto your Kindle Fire.
To use the feature while you are reading a Text-to-Speech enabled e-book, tap the center of the screen and then tap on the menu icon that should appear in the upper right corner of the screen. Go to Additional Settings by tapping there, and then tap the switch that is displayed beside the words Text-to-Speech. Now the feature should be on and ready to use.
With that feature activated, when you’re reading a book, tap the screen to display the progress bar. Then tap the Play Button next to the progress bar. Now the text should be read out loud to you. To listen you’ll need to have external speakers hooked up to whatever kind of device you are using, or you can listen through ear buds or headphones that are plugged into the device’s headphone jack. If you want to increase or slow down the speed of the reading, tap the Narration Speed icon and set it to your personal listing speed preference. The Narration Speed icon looks like this:
If you are reading a book that is in a different language, that’s no problem. Tap the download prompt of the progress bar to install the Text-to-Speech voice in that particular language. The Text-to-Speech supports most commonly spoken languages, and this feature can be really fun to use if you are training yourself to learn a new language. You can listen to your favorite e-books, spoken in that language, which is a great way to practice hearing a new language and identifying the words you hear.
