Your iPhone or iPad can read to you. Enabling the Speak option makes it possible for your iOS device to read aloud any selectable text. Launch the Settings app, tap on General, and then choose Accessibility. Scroll down to Speak Selection, and tap to turn it on.
Now, go into any app where you can highlight text. Your options include Mail, Safari, Notes, and many others. Select some text, and you’ll see a new option appear in the contextual menu (you may have to tap the right arrow to view more options). Tap the Speak command, and your iOS device will start reading the text aloud.
