An Introduction to AAC Augmentative and Alternative Communication (AAC) is simply any way of communicating that supports or replaces spoken words. It can be as simple as a gesture or picture, or as complex as a high‑tech speech‑generating device. At its heart, AAC is about giving people a reliable way to express themselves, connect with others, and participate fully in their world. AAC is not a last resort. It’s not cheating. It’s not only for children who “aren’t talking yet.” AAC is a language access tool, and when we provide it early, consistently, and with confidence, we open the door to communication growth.

Who AAC is for:

AAC supports people who:

• Are late to develop spoken language
• Have motor challenges that make speech difficult
• Have apraxia, autism, Down syndrome, or other developmental differences
• Communicate inconsistently or rely heavily on gestures
• Need a bridge while speech develops
• Benefit from visual language support

AAC is not about replacing speech — it’s about supporting communication in all forms. Many AAC users develop more speech once they have a reliable way to express themselves.

​

Common Myths About AAC

• “AAC will stop my child from talking.” Research shows the opposite — AAC often increases speech because it reduces frustration and builds language skills.
• “AAC is only for non‑speakers.” AAC helps anyone who needs support to communicate clearly, consistently, or confidently.
• “They’re not ready for AAC.” If someone is communicating through gestures, sounds, or behaviours, they are already ready.
• “AAC is too complicated.” AAC becomes simple when we model it naturally during everyday routines.

How to Start Modelling AAC at Home or School

AAC modelling means you use the AAC system while you talk, showing the person how it works without expecting them to copy you.

Start small:

• Model one or two words during routines
• Use core words like go, stop, help, want, more
• Keep the device or board nearby
• Celebrate any communication attempt
• Focus on connection, not correctness

AAC modelling is not a lesson — it’s a habit.

​

Why AAC Matters

AAC gives people:

• Autonomy
• Safety
• Connection
• Participation
• A voice that others can hear and understand

When we provide AAC early and model it consistently, we build a communication environment where the person feels capable, supported, and understood.
