Communication is how we connect, share, and feel understood. But when speech is hard or not yet possible, it doesn’t mean communication has to stop.
Augmentative and Alternative Communication (AAC) are tools and strategies that help children express themselves in ways that feel right for them, whether through pictures, signs, or technology, so they can be heard, understood, and included.
AAC Basics: Types and Uses
AAC encompasses a wide range of tools and techniques designed to support or replace spoken language. It helps people of all ages communicate clearly and participate actively in daily life.
There are two primary categories of AAC:
Unaided AAC: Includes methods that don't require additional tools such as gestures, facial expressions, sign language, or body language.
Aided AAC: Involves using external supports, ranging from simple communication boards and picture symbols to high-tech electronic devices and speech-generating tools like on an iPad.
Augmentative and Alternative Communication (AAC) is flexible and personalized to fit each child’s needs, helping them communicate in ways that work best for them and build stronger connections with others.
Who Can Benefit from an Augmentive and Alternative Communication Device?
AAC is beneficial for individuals who experience challenges in verbal communication, which can include:
Autism Spectrum Disorder (ASD)
Apraxia of Speech
Stuttering
Cerebral palsy
Developmental delays
Neurological conditions such as stroke or brain injury
Severe speech or language impairments
AAC empowers users by enhancing their ability to communicate desires, feelings, and thoughts clearly, significantly improving their quality of life.
Recognising Your Child’s Communication Needs
You might consider AAC support if your child:
Has limited speech or communication
Becomes easily frustrated by how hard it is to express themselves
Shows clear understanding in conversation but is struggling to participate
Experiences significant delays in speech development despite intervention
Early introduction to AAC can significantly enhance language development, reduce frustration, and improve your child's ability to engage socially and academically.
An experienced Speech-Language Pathologist shares:
“AAC isn’t about replacing speech. It’s about giving everyone a way to communicate. For many, it opens the door to spoken words, builds confidence, and makes sure their voice is always heard, in whatever form it takes.”
