Start with the person, not the device
An augmentative and alternative communication (AAC) device helps a person express themselves. It might let them select words or symbols, type a message, or produce speech. People use these tools in different ways, and a device is only one part of how someone may communicate. Gestures, facial expressions, writing and spoken words may all be part of the same conversation.
Greet the person directly, introduce yourself if needed, and speak to them rather than to a companion. Use your usual tone and vocabulary unless they ask you to do otherwise. A device does not tell you what someone understands, what they want to discuss, or how much help they need. The simplest way to find out what works is to pay attention to the individual.
Make room for a different pace
Composing a message may take time, especially when someone is finding words, navigating between screens or dealing with a noisy environment. Ask one question at a time, then leave space for an answer. A comfortable pause can feel long if you are used to quick replies, but filling it with guesses or another question may make it harder for the person to finish.
Keep your attention on the conversation while they compose. You can wait without staring at the screen or trying to read an unfinished message. If you need to move on because of a genuine time limit, say so plainly and offer a way to continue later. For example: “I have a few minutes now, and I’d like to hear your thoughts. If we need more time, can we pick this up after the meeting?”
Let them lead their own message
It can be tempting to finish a sentence or offer several possible answers. Sometimes that helps; sometimes it interrupts a thought or steers the answer toward what you expect. Rather than assuming, ask: “Would you like me to guess, or would you prefer that I wait?” Follow their preference, and be willing to change course if it is not working.
Do not press buttons, take hold of the device or change its settings without permission. For many users, the device is a personal means of expression, not shared equipment. If a support person is present, they may help with positioning or access, but the conversation should still center on what the AAC user communicates. Avoid treating a companion’s interpretation as a substitute for the person’s own words when the person can answer for themselves.
Check understanding without making it a test
Misunderstandings happen in every conversation. If you miss a message, say what you did understand and ask about the part you did not. “I heard that Tuesday works, but I missed the time. Could you tell me again?” is more useful than pretending to understand. If a message surprises you, respond to its meaning rather than commenting on how it was produced.
A device may not always be available or convenient. The person might choose a gesture, a short typed note or a yes-or-no response instead. Ask how they would like to continue rather than deciding for them. Questions with clear options can be useful when the person wants them, but leave room for an answer you did not anticipate. A question such as “Would you rather meet here, somewhere quieter, or somewhere else?” keeps more possibilities open.
Include the person in group conversations
Fast-moving discussions can leave little room to compose a response. In a meeting, class or social gathering, try not to treat the first silence as a sign that everyone has finished. Pause before changing topics, and give the person a chance to signal that they want to contribute. If you are facilitating, you might share the topic in advance, keep questions visible, or return to a point after they have had time to respond.
Respect the person’s control over what they share. Do not read their screen aloud, repeat a private message to the group or explain their communication method to others without asking. The goal is not to make every exchange perfectly smooth. It is to create enough time, attention and choice for a real exchange—one in which the AAC user can start a topic, change their mind, make a joke or disagree, just like anyone else.
