Multimodal Communication: Why “More Than One Way” Is the Goal

If you’ve ever thought “They can say it sometimes… but not always,” you’re not alone.

Many people don’t communicate the same way in every moment. Sometimes speech is easier. Sometimes it disappears—especially with stress, fatigue, sensory overload, illness, anxiety, or complex environments.

That’s where multimodal communication comes in.

Multimodal communication means using more than one way to communicate, so a person can still be understood even when one method (like speech) isn’t working well.

What is multimodal communication?

Multimodal communication is the use of multiple communication methods—often in combination—to express messages.

“Modes” can include:

• spoken words
• gestures and pointing
• facial expressions and body language
• sign-supported communication
• pictures or symbols
• communication boards or books
• AAC apps or speech-generating devices
• writing or typing
• drawing
• yes/no cards or choice boards

It’s not about picking one “perfect” method. It’s about having options.

Why “more than one way” helps

Multimodal communication works because it reduces pressure on any single skill.

1) It makes communication more reliable

If speech is inconsistent (common in many communication profiles), having another mode available means the person can still communicate:

• needs (“help”, “stop”, “bathroom”)
• choices (“this one”, “not that”)
• feelings (“too loud”, “tired”, “worried”)
• ideas and opinions

2) It lowers frustration and misunderstandings

When people can’t get their message across, frustration builds quickly—for the communicator and everyone around them. Multiple modes help reduce “guessing games.”

3) It supports participation in real life

Different settings demand different communication.

• A quiet home is easier than a noisy classroom.
• A familiar person is easier than a stranger.
• A calm day is easier than a rushed day.

Multimodal communication gives people tools to participate across all of these.

4) It supports language growth

For many people, having visual supports (pictures/words on a board or device) can make language easier to learn and use—especially when paired with consistent modeling from communication partners.

Is multimodal communication the same as AAC?

AAC (Augmentative and Alternative Communication) is often part of multimodal communication—but not always.

Think of it like this:

• Multimodal communication = the whole toolbox
• AAC = a powerful part of that toolbox (boards, apps, speech-generating devices, etc.)

Many people use AAC alongside speech, gestures, and other supports. That’s very normal—and often ideal.

What multimodal communication can look like (real examples)

Multimodal communication is often simple and practical.

A child might:

• point to a snack
• say “cookie”
• sign “more”
• tap “want cookie” on a communication board

A teen might:

• speak when comfortable
• text when overwhelmed
• use a core word board at school for quick messages

An adult might:

• speak in short phrases
• use gestures and writing at medical appointments
• use an AAC app when fatigue makes speech unclear

The goal is the same: be understood.

Why speech can be “there one day and gone the next”

Inconsistency can happen for lots of reasons, including:

• sensory overload
• fatigue or illness
• anxiety or pressure to perform
• motor planning demands (getting the mouth to do what the brain wants)
• fast-paced environments (not enough processing time)
• communication breakdowns (feeling misunderstood)

This isn’t about “not trying.” For many people, communication is heavily affected by context and capacity.

Multimodal supports are a way to work with that reality—kindly and effectively.

How to support multimodal communication (without making it awkward)

A big part of multimodal success is what communication partners do. Here are a few supports that help most people:

Model the mode you want to grow

If there’s a communication board or AAC system, use it while you speak. Modeling shows “this is how we communicate here,” without pressure.

Give extra wait time

Many people need more processing time than we expect. Waiting (even 5–10 seconds) can make a huge difference.

Respond to the message, not the method

If someone points, types, signs, or uses AAC—respond as if they “said it” with speech. That reinforces that communication works.

Offer choices that are real and respectful

Instead of “Use your words,” try:

• “Do you want A or B?”
• “Show me.”
• “Point or tap it.”

Keep tools accessible

A board in a drawer doesn’t help. A device that’s flat isn’t easy to see. Accessibility matters as much as the tool itself.

When multimodal communication is especially helpful

Multimodal supports are often useful when:

• speech is emerging or inconsistent
• someone is frequently misunderstood
• communication breaks down during stress
• transitions and routines are hard (home or school)
• social connection is limited by communication barriers
• a person needs reliable communication for safety or healthcare

If any of that feels familiar, it may be worth talking with an SLP about a support plan.

How a speech therapist can help with multimodal communication

An SLP can help you:

• identify which modes already work best
• add supports that fit the person (low-tech and/or high-tech)
• build functional language (not just drills)
• coach caregivers/teachers/partners to model and respond consistently
• make sure communication supports work across environments

This doesn’t have to be a big, overwhelming project. For many families, the first step is simply clarifying a realistic “starter set” of supports.
