Why Use AAC for Toddlers or Children?

AAC devices are augmentative/alternative communication systems that allow a person to communicate with those around them without speaking.  There are many different types of AAC but the most common are high-tech AAC Devices that allow a person to push a button to speak a message.  These are helpful for children or adults who have either lost the ability to speak or who are not able to speak well enough to clearly communicate everything that they want to say.

So why would you need to use AAC with a toddler or child and how does it work?

Why to Use AAC Podcast:

Today we're talking about how, when, and why to use AAC or augmentative-alternative communication devices and systems.  AAC allows children who are not able to talk to use something else to communicate with those around them.  Every child has the right to communication and it is our job as speech-language pathologists to figure out a way for every child to do just that.

This podcast will go over the basics of what is AAC, how to use it to help a child communicate, when it is appropriate to use AAC, and why it should be considered as an option for non-verbal and minimally-verbal children.  Click the play button below to hear the whole podcast, or scroll down to read the quick notes:

What is Augmentative/Alternative Communication (AAC)?

AAC is the term used to describe any form of communication that a person can use that is not speech.  This may include pointing to pictures of what the person wants, using sign language, or using a device that will speak a message when a specific button is pushed.

When Should AAC be Considered for a Child?

AAC should be considered for any child when his/her speech output is not adequate to communicate everything that the child wants/needs to communicate.

Things to consider:

• Child's frustration levels


• Adult frustration levels


• Access to school curriculum


• Participation in classroom activities


• Ability to demonstrate knowledge to teachers


• Access to home and community environment


• Ability to interact appropriately with family and peers


• Independence in developmentally-appropriate daily activities

 What Prerequisite Skills Does a Child Need Before Trying AAC?

In short, there are no skills that a child MUST have before AAC can be tried.  Though, here are a few of the common misconceptions about this:

These are commonly used as excuses why AAC devices should not be attempted with children but these are WRONG:

• The child must understand cause and effect (AAC teaches cause and effect quite effectively)


• The child must understand that a picture represents an object (again, AAC teaches this)


• Child must have good enough motor skills for AAC (there are lots of alternatives for children who can't access a device with their hands)


• Child must understand enough language for AAC use (babies don't have great language before they are introduced to speech)


• Child must be interested in communicating (even inappropriate behaviors can be shaped into intentional communication)
