If you need to adjust the settings in Osmo ABCs, you can do so at any time from the Main Menu in the game.
To do so, tap the Pause button, then tap the Home icon to return to the Main Menu.
From there, tap the Gear icon (settings icon) in the upper left corner to access the Difficulty, Phonics, Hints, and Sound settings. The settings will update in the game once you begin a new postcard.
