How to Model Language using AAC

For many individuals who use augmentative and alternative communication (AAC), consistent modeling from communication partners is essential for developing language skills. However, one of the most common concerns from parents, educators, and therapists is how to model AAC without making interactions feel forced or unnatural. The goal is to integrate AAC into authentic conversations so that it enhances — not interrupts — communication.

Why Modeling Matters

AAC modeling, also called aided language stimulation, involves using the AAC system yourself to show the communicator how words and phrases can be expressed. Just as young children learn spoken language by hearing it used in real contexts, AAC users learn more effectively when they see their device in action. Regular modeling builds vocabulary, demonstrates sentence structure, and helps normalize device use in everyday life.

Strategies for Seamless AAC Modeling

1. Model Alongside Speech

Continue speaking naturally while pointing to symbols or typing on the AAC system. Your verbal speech provides a complete language model, while your AAC use shows how to produce it. This dual input ensures that communication remains flowing and interactive.

2. Focus on Key Words, Not Every Word

You don’t need to model every single word in a sentence. Highlight core vocabulary — such as “want,” “go,” “more,” “help,” “stop” — that can be combined to create many messages. For example:

• Spoken: “Do you want more juice?”

• AAC: model want + more

This keeps the conversation moving and reduces pauses.

3. Use Natural Pauses, Not Long Breaks

Insert AAC modeling during brief conversational pauses rather than halting the interaction. Over time, you’ll develop a rhythm where device use feels like part of the flow rather than a separate task.

4. Respond to Interests and Actions

Follow the communicator’s lead. If they’re looking at a book, model words like “look,” “page,” or “funny.” If they’re building with blocks, model “big,” “fall,” or “more.” By connecting your modeling to what’s happening in the moment, the interaction feels authentic.

5. Balance Modeling With Listening

AAC is about two-way communication. Be sure to give space for the individual to respond, whether through their AAC device, gestures, vocalizations, or facial expressions. Sometimes, simply waiting is the most powerful tool you have.

6. Use Multiple Opportunities Throughout the Day

Model during routines, play, shared reading, mealtimes, or transitions. Short, frequent modeling opportunities are often more effective than one long “practice session.”

Practical Opportunities for AAC Modeling

AAC modeling can happen anywhere — not just during therapy. Here are some ways to integrate it naturally:

• Toy Play: Model words like “go,” “stop,” “big,” “fast,” or “help” while playing with cars, dolls, or building blocks.

• Sensory Motor Activities: Use words like “swing,” “more,” “fast,” “slow,” “jump,” or “stop” during movement-based play.

• Watching Videos: Model “funny,” “like,” “more,” “stop,” “go,” or “look” while enjoying a favorite show together.

• Daily Routines: During cooking, cleaning, or self-care, model words like “wash,” “dry,” “cook,” “mix,” “clean,” “on,” “off,” or “ready.”
  

These real-life contexts make language meaningful and give the AAC user more chances to see how words fit into everyday situations.

Common Pitfalls to Avoid

• Over-correcting: Avoid interrupting to “fix” grammar or vocabulary — focus on communication, not perfection.

• Taking Over the Conversation: If you use the AAC device more than the communicator does, you risk limiting their opportunities to take the lead.

• Making It a Drill: Keep modeling contextual and meaningful, not repetitive for its own sake.

Final Thoughts

When modeling AAC is woven seamlessly into natural conversation, it supports language growth without disrupting the flow of interaction. The key is to be responsive, intentional, and consistent. Over time, your modeling will not only expand vocabulary and sentence skills — it will also help AAC use become a natural and valued part of everyday communication.
