Our Perspective

"We know the heartbreak of seeing a child struggle to express their basic needs. At Buzz ABA, we believe every child deserves a voice. AAC isn't just about technology; it's about connection. We've seen firsthand how finding the right communication tool can transform frustration into confidence and open up a whole new world for families."

Augmentative and Alternative Communication (AAC) encompasses all forms of communication beyond speech that help people express themselves. According to the American Speech-Language-Hearing Association (ASHA), AAC does not prevent or delay speech development.

Understanding AAC: More Than Just Devices

AAC includes a wide range of tools and strategies:

  • Unaided AAC: Body language, gestures, facial expressions, sign language
  • Low-tech AAC: Picture boards, communication books, PECS
  • Mid-tech AAC: Simple voice output devices, recorded message buttons
  • High-tech AAC: Tablets with communication apps, dedicated speech-generating devices

The PECS System

The Picture Exchange Communication System (PECS) is one of the most widely used AAC approaches for autistic children. It follows six phases:

Phase 1-3: Foundations

  • 1. Exchanging single picture for item
  • 2. Generalizing across distance/people
  • 3. Discriminating between pictures

Phase 4-6: Advanced Skills

  • 4. Building sentences ("I want...")
  • 5. Answering "What do you want?"
  • 6. Commenting and responding

High-Tech AAC: Communication Apps

Tablet-based apps have revolutionized AAC. Popular options include:

  • Proloquo2Go: Comprehensive symbol-based app, highly customizable.
  • TouchChat: Customizable with multiple page sets and vocabularies.
  • LAMP Words for Life: Based on Language Acquisition through Motor Planning.
  • TD Snap: Symbol and text-based with robust vocabulary options.

Clinical Director's Insight

"Communication is a fundamental human right, and AAC opens doors for children who struggle with verbal speech. With my background in verbal behavior and functional communication training, I've seen how AAC doesn't replace speech—it often supports it. When children can finally express their needs and connect with others, it transforms their entire world."

Implementing AAC Successfully

  • 1.Model AAC use constantly: Show your child how to use the device in natural contexts.
  • 2.Make AAC available everywhere: The device should always be within reach, not just during 'therapy time'.
  • 3.Honor all communication attempts: Respond to AAC use immediately to reinforce the behavior.
  • 4.Train all partners: Teachers, therapists, grandparents, and siblings should all know how to support use.

Frequently Asked Questions

Will AAC prevent my child from learning to talk?

No. Research consistently shows that AAC does not prevent or delay speech development. It often supports verbal communication by reducing frustration and modeling language structure.

When should we start AAC?

There is no prerequisite skill level for AAC - it can be introduced as soon as a communication need is identified. Early intervention is key to preventing frustration and behavioral challenges.

Will insurance cover an AAC device?

Many insurance plans cover AAC devices as durable medical equipment when medical necessity is documented by a Speech-Language Pathologist (SLP). Our team can help guide you through this process.
