Getting Started with AAC: A Guide for Families

Augmentative and alternative communication (AAC) is any tool or strategy that helps someone communicate when speech alone is not enough. AAC ranges from simple paper boards and picture cards to powerful apps and dedicated speech-generating devices that speak aloud at the touch of a button or a glance of the eyes. If your family is just beginning this journey, the number of choices can feel overwhelming. This guide breaks the early steps into a manageable order.

AAC does not stop speech — it supports it

A common worry is that giving someone a device will keep them from talking. Decades of research point the other way: AAC tends to support spoken language rather than replace it, because it lowers the pressure to perform and gives the person a reliable way to be understood. The goal of AAC is communication in every form — gestures, vocalizations, words, and the device all count.

Start with a speech-language pathologist

An AAC evaluation by a speech-language pathologist (SLP), ideally one who specializes in AAC, is the single most valuable first step. The SLP matches the person’s motor, vision, and language abilities to the right vocabulary and access method, and can help with funding paperwork. Many devices are covered by insurance or Medicaid in the United States when an SLP documents the need.

Understand the two big choices

Almost every AAC decision comes down to two questions: what vocabulary, and what access method.

• Vocabulary: Symbol-based systems (pictures plus words) suit emerging communicators, while text-based systems suit people who can spell. Robust systems such as LAMP Words for Life, Unity, Super Core, and the Crescendo vocabulary in Proloquo2Go are designed to grow with the user rather than being outgrown.
• Access method: How will the person select buttons? Direct touch is most common, but eye gaze, switch scanning, and head tracking open AAC to people who cannot reliably touch a screen.

Model, model, model

The most powerful thing a communication partner can do is use the AAC system themselves. This is called aided language modeling: as you talk, you also press the matching buttons on the device. Children learn spoken language by hearing thousands of words before they say their own; AAC users need to see their system used the same way. Aim to model without demanding a response, and celebrate every attempt.

Give it time and keep it available

A device only helps if it is within reach during real moments — meals, play, bedtime, frustration, and joy. Keep it charged, keep it nearby, and resist the urge to put it away when things get busy. Learning a language takes years, not weeks, so progress is measured in months.
