Whether you're driving or you just want to be hands-free around the house, you can make your iOS device read anything from emails to websites to articles, and all it takes is turning on an Accessibility function. As How-to Geek explains, your device's "Speak Screen" feature lets you command it to read just about anything with a quick swipe. We've told you how to enable your phone's text-to-speech function before, but this option makes it even easier.
They explain how it works:
With the "Speak Screen" feature in iOS, you can have your device read whatever's on the screen to you just by swiping two fingers down from the top of the page. It can read just about anything, from settings pages to web sites to ebooks. While it's obviously useful if you have some form of visual impairment, it can also be really handy when you want to catch up on your reading but don't want your eyes glued to a screen.
To enable it, simply head to Settings > General > Accessibility > Speech. Then, enable "Speak Screen". From there, you should be able to swipe down from any screen and your device will start reading. A small toolbar will pop up, allowing you to adjust the speed and pause directly from the screen. For more detail, head to the post below.
