When aphasia affects someone’s ability to express themselves, connect with loved ones, or participate in daily conversations, communication can feel overwhelming. Augmentative and Alternative Communication (AAC) tools offer a pathway that can support expression, comprehension, and confidence while honoring the person’s abilities and communication style.

For many people with aphasia, AAC may provide a sense of independence and help make conversations more accessible at home, in the community, and during social interactions.

What Is an Augmentative and Alternative Communication (AAC) Tool?

AAC refers to any method or system that supplements or replaces spoken language. It is used by many individuals who experience difficulty communicating due to conditions such as aphasia, stroke, or head injury. AAC may include simple communication aids, low-tech or highly advanced devices, depending on a person’s needs.

Importantly, AAC is designed to support communication. Many people with aphasia use AAC alongside speech therapy and other rehabilitation approaches.

How AAC Tools Help People with Aphasia Communicate

Because aphasia affects people differently, AAC is always customized. What works for one person may not work for another, which is why guidance from a trained professional is so valuable.

AAC tools may help people with aphasia:

• Express needs, wants, and preferences
• Participate in conversations more confidently
• Understand written or spoken information
• Reduce frustration during communication breakdowns
• Practice language skills in supportive, structured ways

Different AAC Models Explained

AAC tools typically fall into two main categories: low-tech and high-tech. Both can be beneficial, and many people use a combination of the two.

Choosing Between a Low-Tech and High-Tech AAC

Selecting an AAC tool usually depends on a person’s physical abilities, cognitive needs, communication goals, and comfort with technology. A speech-language pathologist or communication specialist can help determine which options are the best fit.

Low-Tech AAC tools do not require batteries or electronics. Low-tech AAC may support communication during moments when speaking is more challenging, such as periods of fatigue or word-finding difficulty.

High-Tech AAC tools involve digital devices or software that allow users to type, select images, or use speech-generating technology. These tools may be helpful for people who want more robust features, such as customizable vocabulary, voice output, or interactive communication pages.

Helpful AAC Tools to Consider

Every AAC tool can be adapted or customized so the user feels confident and supported. Below are examples of AAC tools commonly used by people with aphasia:

• Picture-based communication boards: These may include symbols, words, or photos that someone can point to when expressing needs or ideas.
• Letter boards or alphabet charts: Useful for spelling words or offering first-letter cues when speaking.
• Low-tech communication books: Personalized books containing important phrases, pictures, or conversation starters.
• Speech-generating devices (SGDs): These electronic devices produce spoken words or sentences when the user selects icons or types text.
• Tablet-based AAC apps: Many apps offer exercises, communication pages, and voice output that may help support language practice and everyday conversation.
• Text-to-speech tools: Helpful for individuals who can type but may have difficulty speaking clearly.
• Writing or drawing pads: Simple tools that can supplement verbal communication when needed.

The Difference an AAC Tool Can Make

AAC may support communication in meaningful and practical ways. For example, someone might use a low-tech board to order at a restaurant, a tablet app to participate in a book club, or a speech-generating device to share a story with a grandchild.

Over time, AAC use may help improve communication participation, reduce frustration, and encourage social engagement. Families often report that AAC gives them new opportunities to connect and share experiences.
