AAC: Tools That Make Communication Possible – Neurodiverse Collaborative Network

What is AAC?

AAC stands for Augmentative and Alternative Communication. It includes any tool or method that helps a person communicate when speech alone is not enough or not reliable. AAC can be simple and low-cost, or it can involve technology. It is not a last resort — it is a communication tool, just like a pen or a phone.

Low-tech and high-tech AAC

Low-tech AAC does not require a battery or a screen — picture boards, letter charts, communication books, and symbol cards. High-tech AAC uses devices and apps that generate speech when a person selects symbols, pictures, or typed text. Well-known apps include Proloquo2Go, TouchChat, and Snap Core First. Many insurance plans cover speech-generating devices when recommended by an SLP.

Tips for families

Model the use of AAC yourself — this is called aided language input. Give the person time to respond; AAC takes more effort than talking and rushing shuts down communication. Treat AAC as a real voice. What someone communicates through their device or board deserves the same respect as spoken words.
