Whether you're having trouble reading small text on your screen or want to hear text read aloud while you're busy with something, you can easily have Siri read you text aloud, and it can also read text from almost any screen or app, but before that you need to Enable the feature in settings.
How to make Siri read text on iPhone and iPad
First you have to enable the feature in settings:
◉ On the iPhone and iPad, go to Settings, then Accessibility.
◉ Tap on the spoken content.
◉ Activate Speak Screen.
Once you enable this setting, simply open the app you want to hear read aloud and say, “Hey Siri, speak screen.” Alternatively, you can swipe down from the top of the screen with two fingers to have Siri read the screen text.
Siri will read what's on the screen, and you should also see a popup control, which you can use to pause or play, vary the playback speed, and skip sentences. After a few moments, the control will be minimized to the side of the screen, and you can tap it to take it back at any time.
