How do I change the playback speed?

Do you think the narrator is reading too fast or too slow? No problem, you can of course change the playback speed. In the bottom of the audio player, you find a button that always shows you the current speed. By default, it will be set to "1.00x" which is the original speed of the book.

Tap this button and adjust your speed to as slow as 0.50x and as fast as 2.00x.
