Augmentative and Alternative Communication (AAC

Helping Every Child Find Their Voice

Children with significant speech, language, and communication challenges benefit from assistive/external methods to help them communicate effectively. Needs range from a reduction in spoken understandability to non-speaking. These assistive/external methods are collectively known as Augmentative and Alternative Communication (AAC). AAC includes a wide range of communication tools and strategies designed to supplement verbal speech and gestures.

AAC benefits include:

  • A tangible, external communication option when speech is limited
  • A means to further develop the child’s language skills
  • Another way for children to connect more effectively with others
  • A visual point of reference in understanding the child’s needs and wants
  • The use of personalized symbols or pictures that are easily recognizable
  • A means to reduce frustration in not being understood
  • A means to not only initiate language, but also respond and clarify messages

It’s important to reassure parents/caregivers that the introduction of AAC support does not hinder speech or verbal development. In fact, we generally find that AAC encourages spoken language, while also providing children a more effective means to communicate.

AAC Options

Low-tech AAC includes the use of tangible symbols/pictures that a child can point to in order to greet, request, ask/answer questions, comment, etc. Examples include the use of a Picture Exchange Communication System known as PECS. Preschool-age children often start with a low tech AAC program and then may transition to a high-tech speech generating device.

High-tech AAC systems include the use of switches, speech-generating devices, and applications on tablets. Commonly used AAC software programs include Proloquo2Go, TD Snap, and Touch Chat. These high tech systems offer robust vocabulary and can be customized to the needs of the child.

Individualized Assessment and Support

Selecting the right AAC system requires a comprehensive team-based approach. We work closely with families and professional team members to implement tools that suit each child’s strengths and needs. Trials with different AAC systems may be needed to determine the best fit for a child. AAC systems require plenty of exposure, modeling, and practice opportunities across varied everyday settings. We support children as they build confidence using their AAC system in everyday life. Our SLPs are committed to providing family-centered, individualized support for AAC implementation to ensure that every child has a voice.

Every child deserves a way to express their thoughts, needs, and feelings—and AAC helps make that possible.
