What is AAC? An Introduction for Parents and Professionals

Written By Katrina Fulcher

Communication is at the heart of every relationship, but speaking can be challenging for some people. That's where augmentative and alternative communication (AAC) comes in, providing a valuable way for those with difficulty with spoken language to express themselves. Whether you're a parent wanting to learn how AAC can help your child or a professional curious about its uses, this guide will break down what AAC is and how it can make a real difference.

What is AAC?

Augmentative and alternative communication (AAC) is a tool, system, or strategies that support or replace spoken language for individuals who cannot rely on speech alone. AAC can range from simple, no-tech options like picture cards to advanced, high-tech devices with dynamic screens and voice output capabilities (American Speech-Language-Hearing Association [ASHA], 2023).

Think of AAC as a way to bridge the gap between a person’s thoughts and the world around them. It empowers individuals to express their needs, share their feelings, and participate in conversations, fostering independence and inclusion.

Examples of AAC Systems

AAC systems are as diverse as the individuals who use them. Here are some examples:

1. No-Tech Options:

  • Examples: Picture exchange systems, communication boards, and written messages.

  • Who Benefits: These tools work best for people who like hands-on, tactile approaches or don’t have easy access to technology.

2. Low-Tech Options:

  • Examples: Static boards with pre-printed symbols or portable voice-output devices with limited customization.

  • Who Benefits: Ideal for those who need something easy to carry around and simple to use.

3. High-Tech Options:

  • Examples: Speech-generating devices (SGDs) with dynamic screens, tablet apps, or eye-tracking devices.

  • Who Benefits: Tailored for individuals who need a more flexible, feature-packed communication system.

Who Uses AAC?

AAC is for anyone who experiences difficulty communicating through speech alone. It includes but is not limited to individuals with:

  • Conditions like autism or cerebral palsy that affect development

  • Neurological disorders like ALS (Lou Gehrig’s disease) or stroke

  • Temporary conditions such as intubation following surgery

AAC is not just for individuals who do not use their voice or conventional speech to communicate; it can also enhance communication for any person who has difficulty understanding language or using language to interact with various partners across multiple contexts, helping them share their needs, wants, and thoughts more effectively.

Benefits of AAC

Research consistently shows that AAC can:

  • Improve communication skills, allowing individuals to express themselves more effectively (ASHA, 2023)

  • Enhance social interactions by enabling participation in conversations (AssistiveWare, 2023)

  • Support language development, particularly in children (Lingraphica, 2023)

  • Boost self-esteem and confidence by giving users a way to be heard (Communication Matters, 2023)

AAC is not a “last resort”—it’s a tool for empowerment, enabling individuals to live fuller, more connected lives (AssistiveWare, 2023).

What’s the Big Picture?

The big takeaway about AAC is that it’s a powerful way to enhance communication and foster independence for individuals with diverse needs. For speech-language pathologists, the key action is to view AAC as a customizable, evolving solution that meets each individual's unique needs. Parents and caregivers should focus on embracing AAC to empower their loved ones to express their thoughts, needs, and dreams. Together, we can create opportunities for meaningful communication that build confidence, foster relationships, and enrich lives.
