Communication is more than just spoken words. For many children, especially those who are nonverbal, minimally verbal, or have complex communication needs, AAC (Augmentative and Alternative Communication) provides a voice when speech is difficult or doesn’t develop typically.
In this blog, we’ll explain what AAC is, how it can help children connect with the world around them, and how speech pathologists support families through assessment, training, and NDIS funding applications.
What Is AAC?
AAC stands for Augmentative and Alternative Communication. It refers to any method of communication used to supplement or replace speech. AAC includes:
Unaided systems: Gestures, sign language, facial expressions
Low-tech options: Picture boards, visual schedules, communication books
High-tech devices: Tablets or dedicated speech-generating devices (SGDs) with voice output
AAC is not a “last resort”—it’s a powerful tool that allows individuals to express themselves, make choices, build relationships, and participate in everyday life.
Who Might Benefit From AAC?
Children with a range of diagnoses and needs may benefit from AAC, including:
Autism Spectrum Disorder (ASD)
Developmental delays
Down syndrome
Childhood apraxia of speech
Cerebral palsy
Genetic conditions
Traumatic brain injury
Some children may use AAC temporarily, while others may rely on it long-term as their primary means of communication.
Common Myths About AAC
Myth: AAC will stop my child from talking.
Truth: AAC actually supports spoken language development. Children are more likely to speak when they have a reliable way to communicate without pressure.
Myth: My child is too young or not ready for AAC.
Truth: AAC can be introduced as early as toddlerhood. The earlier we give a child a voice, the better.
Myth: AAC is only for children with no speech.
Truth: AAC helps children with limited or unclear speech be understood—and reduces frustration.
How Speech Pathologists Support AAC
At South Coast Therapy & Support Group, our speech pathologists guide families through every step of the AAC journey:
Assessment
We assess communication needs, motor skills, cognitive skills, and environments to determine the best AAC options.
Trials of Devices
We coordinate device trials through trusted suppliers to explore what works best in real-life settings.
NDIS Reporting and Applications
We prepare evidence-based reports and quotes to support mid- and high-cost AAC applications under the NDIS, including:
Functional communication assessments
Trial summaries
Risk assessments
Training and implementation plans
Training and Ongoing Support
We train parents, carers, educators, and support workers to use the AAC system consistently across home, school, and community settings.
AAC and the NDIS
AAC devices can be funded through the Assistive Technology and Improved Daily Living categories of your child’s NDIS plan. Our reports ensure your application is aligned with NDIA requirements, and we provide clear documentation for plan reviews or equipment renewals.
Our Approach to AAC
Individualised: We match the AAC system to the child—not the other way around.
Family-centred: We involve families every step of the way.
Inclusive: We work with schools, preschools, and therapy teams to ensure consistency.
Evidence-based and neurodiversity-affirming: We honour each child’s unique communication journey.
Giving Your Child a Voice
Every child deserves a way to be heard. Whether your child is nonverbal, has limited speech, or is difficult to understand, AAC can unlock their ability to connect, express, and thrive.
