Understanding AAC: Giving Voice to Those Who Need It
Augmentative and Alternative Communication (AAC) gives a voice to individuals who cannot rely on speech alone. For children and adults with communication challenges, AAC opens the door to expressing thoughts, building relationships, participating in school, and engaging in everyday life.
In this post, we’ll explain what AAC is, who it helps, the tools it includes, and why it’s a powerful resource for communication..
What is AAC?
AAC, short for Augmentative and Alternative Communication, refers to any method, tool, or strategy that helps people communicate when speech is limited or absent. This can include:
Low-tech options: Picture boards, communication books, or gesture systems
High-tech solutions: Tablets, dedicated speech-generating devices, or computer-based communication software
Symbol-based systems: Images or icons representing words and ideas
Text-based systems: For individuals who can type or spell
AAC is not a “last resort” it can be introduced early to support language growth alongside or in place of speech.
Who Benefits From AAC?
AAC supports people of all ages and diagnoses, including:
Children with Autism Spectrum Disorder (ASD) who struggle with verbal expression
Individuals with Cerebral Palsy or other motor impairments affecting speech
Stroke or brain injury survivors recovering communication skills
People with degenerative conditions like ALS, where speech ability declines over time
Non-verbal individuals of any age who need alternative ways to communicate
Key Components of AAC Systems
Symbols – Pictures, icons, or written words representing concepts
Boards and Devices – From simple paper boards to advanced, speech-generating tablets
Access Methods – Touch, switches, eye gaze, head pointing, or adaptive technology
Language Systems – Symbol-based (e.g., PECS) or text-based systems
Why AAC is Life-Changing
AAC is more than just a tool, it’s a path to independence and inclusion. It allows individuals to:
Express themselves – Share wants, needs, feelings, and ideas
Engage socially – Build relationships and connect with peers
Access education – Fully participate in classroom learning
Make choices – Be part of decision-making in their daily lives
AAC and Early Intervention
Introducing AAC early can support speech development, not hinder it. Many children using AAC also develop verbal skills over time. The earlier AAC is introduced, the more opportunities a child has to communicate, learn, and build confidence.
Next Steps if You Think Your Child Could Benefit from AAC
If you think your child may benefit from AAC:
Schedule an evaluation with a speech-language pathologist trained in AAC.
Discuss options that fit your child’s needs, abilities, and environment.
Learn how to model AAC use during everyday activities so your child sees it as a natural way to communicate.
The earlier AAC is introduced, the more opportunities your child will have to build language skills and confidence.
AAC ensures every voice is heard-spoken or not. It can transform communication, relationships, and learning, giving children and adults the tools they need to connect with the world around them.
