AAC stands for "Augmentative and Alternative Communication." AAC apps are software applications for mobile devices that can help individuals who are non speaking or those whose speech is not usually understood by others. The apps generate speech when a user selects symbols programmed with words or phrases or when they are used to create text.

Symbols/pictures representing a single meaning (select and sequence pictures to generate messages):
Text-based apps (use the alphabet to generate messages):
Combination apps (use both symbols and text):
