Method 1: Select text and speak it

Open Settings → General → Accessibility → Speech and enable Speak Selection.

A Speak button will appear when you select text.

In an app like Reeder, hold down on the text, make a selection or choose Select All, then tap Speak.

Method 2: Speak all text

Open Settings → General → Accessibility → Speech and enable Speak Screen.

Swipe down with two fingers form the top of the screen to hear the content of the screen.

A HUD appears for controlling speech, which hide automatically or with the left arrow and unhidden with the right arrow.
