Augmentative and Alternative Communication (AAC)

If your child has a difficult time speaking or being understood, you may have come across the term AAC. AAC is Augmentative and Alternative Communication. AAC is any method of communication that supports or replaces spoken words. For many autistic children, AAC opens the door to connection and assists in communication.

One of the most common AAC tools used today is a tablet or iPad with a communication app. These apps allow your child to tap on pictures, symbols, or words to “speak” through the device.  For example, your child might press a button with a picture of a cup of water and the iPad will say, “I want water.” These systems are customizable, so over time, your child’s app can be filled with their favorite foods, family members, daily routines, and even personal photos and voice recordings. The technology adapts as your child grows, helping them build a wider vocabulary and more complex sentences when they are ready.

There are many AAC apps available for iPads and tablets. These apps usually include buttons or symbols your child can tap to “speak” using a voice output. Many of the apps available provide free trials as well.

Some common AAC apps include:

• Proloquo2Go
• TouchChat
• LAMP Words for Life

It is a common misconception that AAC hinders communication. Using AAC may even support the development of verbal language in some instances. For some children, AAC becomes their main way to express themselves. For others, it can be a bridge that works alongside spoken words. For some children, AAC is used long-term and consistently. In other cases, it is used short-term or only sometimes when necessary.

If you are wondering whether AAC might be a good fit for your child, it’s something worth discussing with their therapy team. There are also AAC evaluations which would help provide AAC app recommendations tailored to your child’s needs and abilities. A speech language pathologist, BCBA or other provider can assist you with next steps.
