Image and text size can be personalized from Settings —> Change Image & Text Size (select from default - small, medium, and large). Settings —> Configure Image Keyboard allows the user to turn on/off features that allow for the category text to be read aloud (synthetic voice for categories), to keep the user in the category after a image has been selected (stay on category after image selection), and disable the speech output for individual words so that it only reads aloud when the white text screen is touched (synthetic voice disabled for individual words). The AAC board can be modified in Settings —> Manage Board Builder.
