Augmentative and Alternative Communication (AAC)

Hero Image Alt Text

Augmentative and alternative communication (AAC) are the ways people communicate when they have difficulty speaking. It's designed for people of all ages. Augmentative means to add to someone’s speech. Alternative means instead of speech. Some people use AAC all the time because they don’t speak. Some people might use AAC sometimes to help people understand their speech. Some people might need AAC only for a short time, like when they have surgery and can’t talk.

Types of AAC

AAC systems look different because they’re customized for each person.

No-tech and low-tech options can include:

  • drawing
  • facial expressions
  • gestures
  • pointing to pictures and words
  • spelling
  • writing

High-tech options can include:

  • apps on tablets or smartphones
  • computers with artificial voices
  • speech-generating devices

A person might use a combination of AAC tools to communicate throughout the day.

Working With a Speech-Language Pathologist (SLP)

SLPs help people communicate effectively by finding the right types of AAC for you or your loved one. Not every tool works for every person, so it is important to find the right one for you. SLPs can:

  • Assess communication needs and identifying technology that fits those needs.
  • Recommend appropriate AAC technology and tools tailored to you or your loved one’s physical needs.
  • Teach you and or your loved one how to use customized AAC.
  • Teach the people in your life how to communicate with you and include your AAC tools.
  • Work with other professionals—like teachers, occupational therapists, and physical therapists—to make sure you can use AAC wherever you are.

Some AAC tools are covered by insurance, but some are not. An SLP can help you navigate these options.

Common Questions

You might be curious about using AAC. Here are some common questions about using AAC.

  • When can you start using AAC? AAC is for anyone of any age. Children younger than 3 years old can start using AAC. There are no thinking skills, test scores, or other milestones that you need to reach before AAC can help. Even if you tried once before, you can try again. It's never too early or too late to use AAC.
  • How does AAC help speech and language development? AAC helps develop language and enhance speech. Some young people use AAC to learn vocabulary and to read. AAC can help if a person’s speech is hard to understand. People who use AAC can use both speech and AAC to talk to other people.
  • What if I can’t fully use my arms and hands? There are many ways to use AAC. People who have difficulty moving their hands can still use AAC. You can use your arms, feet, head, or eyes to use AAC. Your SLP can work with you and your occupational and physical therapists to help communicate.

If you or a loved one is considering AAC, it's essential to consult with an SLP to find the AAC system that works best for you. SLPs can provide personalized assessments, training, and guidance.
